StemCell Therapy

(HealthDay News) -- A new method to prevent recurrence of deadly glioblastoma brain cancer shows promise, say U.S. scientists.

Radiation can temporarily shrink a glioblastoma tumor, but the cancer nearly always recurs within weeks or months. Few people with this type of brain cancer survive more than two years after diagnosis.

In a study on mice, Stanford University School of Medicine researchers found that blocking access to oxygen and nutrients prevents tumor recurrence.

The first step, they said, was discovering that tumors blasted with radiation use a secondary pathway to generate blood vessels needed for regrowth.

"Under normal circumstances, this pathway is not important for growth of most tumors," senior author Martin Brown, a professor of radiology, said in a Stanford news release. "What we hadn't realized until recently is that radiation meant to kill the cancer cells also destroys the existing blood vessels that nourish the tumor. As a result, it has to rely on a backup blood delivery pathway."

The Stanford team used a molecule called AMD3100 to block the secondary glioblastoma tumor growth process in mice.

The study was published online Feb. 22 in the Journal of Clinical Investigation. Read more...

The Vatican has cancelled a controversial scientific conference that would have featured scientists, including the president of the California stem cell agency, who support human embryonic stem cell research.

The conference reportedly created a "scandal" in the Vatican, according to a report by David Kerr of the Catholic News Agency. Kerr wrote,

"'I am infinitely relieved that the Church has avoided a major blunder which would have confused the faithful for decades to come,'” said one member of the Pontifical Academy who asked for anonymity in commenting to (the Catholic News Agency)."

The Catholic church opposes hESC research because of its belief that it destroys human life.

The conference would have taken place at the Vatican April 25-28 and included an audience with the pope. In addition to an appearance by CIRM's Alan Trounson, the key lecture was scheduled to have been given by George Daley of Harvard.

Kerr quoted the member of the Vactican's Pontifical Academy for Life as saying,

"The Holy Spirit has certainly shown to be present through those faithful members who drew attention to the ambiguity of the choice of speakers. I hope and pray that a review will be affected of the basis on which these congresses are planned."

Kerr also quoted another anonymous member of the academy as saying that the presence of speakers such as Trounson and Daley was "a betrayal of the mission of the academy and a public scandal."

A California stem cell researcher, who must remain anonymous, made the following emailed comment today on the progress report on the $230 million in disease team grants from the California stem cell agency and termination of a $19 million grant.

"I'm impressed that CIRM is following through on monitoring the huge disease team grants and has actually curtailed the funding of one that didn't meet a key milestone. I hope that makes the other grant holders nervous! Too many scientists (in my humble opinion) forget that they need to do what they said they'd do- or - if the first plan fails, have the expertise and desire to adapt and find another way to reach the goals."

The California Stem Cell Report is concluding its coverage today of the meeting of the governing board of the directors meeting of the California stem cell agency.

No decisions were made on the general direction of future funding -- basic research and training vs development of therapies. Some of the directors differed sharply on the issues, however. We will have more on this subject later.

Here are slides from the presentation on the progress report on the agency's $230 million disease team round. One $19 million grant was cancelled.

The $3 billion California stem cell agency announced today that it has hired Kevin McCormack, currently media relations manager at California Pacific Medical Center in San Francisco, as its new director of communications.

CIRM Chairman Jonathan Thomas told the agency's directors at their meeting this morning in Sacramento that the appointment comes "not a moment too soon." Thomas told directors last June that the agency was engaged in a "communications war." Directors have been concerned about the lack of media coverage of the agency, which is largely below the radar of the mainstream media.

Thomas said that McCormack has "lots of experience" in media crisis management and "pressure cooker situations."

McCormack also served as media relations manager, Division of Research at Kaiser Permanente, and was a health/medical producer at KRON-TV in San Francisco.

The agency did not immediately release McCormack's salary. He will begin work April 2.

The California stem cell agency has terminated a $19 million grant to a UC San Francisco researcher involved in the agency's ambitious attempts to push stem cell therapies into clinics.

The agency said the research effort led by Mitchel Berger, chairman of the department of neurological surgery at UCSF, "did not meet a go/no-go milestone" stipulated in the grant. His research was funded in 2010 to treat brain tumors with genetically modified neural brain cells. No further explanation for the termination was provided by CIRM in a report prepared for tomorrow's meeting of the CIRM governing board. The agency estimated the cancellation would save $13 million.

The California Stem Cell Report has asked Berger and his co-PIs for comment on the CIRM action. The other researchers are Evan Snyder of Sanford-Burnham and Webster Cavanee of the Ludwig Cancer Institute. Their remarks will be carried verbatim when they are received.

The CIRM action was disclosed in the progress report on the $230 million disease team effort launched by the agency in 2009. The amount climbed to more than $250 million with contributions from partnering countries. Three of the 14 funded applicants – Irv Weissman and Gary Steinberg, both of Stanford, and Karen Aboody of the City of Hope – were approved only after they appealed to the CIRM board to overturn rejections by grant reviewers. (See  here , here and here for their written appeals. See here and here for coverage of the 2009 board action.)

One other disease team grant was modified to limit its scope and revise its funding. No savings were announced by CIRM. The PI on the $20 million project is Dennis Carson of UC San Diego. Co-PIs are Catriona Jamieson, also of UC San Diego, and John Dick of the University Health Network of Canada. The research is aimed at leukemia.

The actions on the disease team grants were not entirely unexpected. From their inception, CIRM directors have been told not to expect all the grants to finish successfully.

Ellen Feigal, senior vice president for research and development at CIRM, prepared the 19-page update on the disease team efforts. The grants are aimed at generating an investigational new drug application with the FDA within the four-year term of the grant.

She said that the funding decisions were made following evaluation of the projects by panels of clinical development advisors. Their recommendations were then considered by CIRM staff.

Feigal's report laid out accomplishments of the research so far and discussed changes in direction.

She said two companies have been formed since the grants were awarded to commercialize the hoped-for products. She said that in June 2011 Aboody founded TheraBiologics Inc., Newport Beach, Ca., of which she is chief scientific officer and director. Another company, Regenerative Patch Technologies, Glendale, Ca., was created by the team working on an hESC treatment for age-related macular degeneration. That $16 million grant involves Mark Humayan and David Hinton of USC, Dennis Clegg of UC Santa Barbara and Peter Coffey, formerly with University College, London, but now at UC Santa Barbara. The effort has generated seven patent filings.

The Feigal update also discussed the efforts of companies involved in other disease team grants. The lack of CIRM funding for biotech firms has been a bone of contention with industry and troublesome for some CIRM directors.

CIRM indicated the projects involving the firms were moving on schedule with no major difficulties reported. The companies involved are ViaCyte of San Diego, Calimmune of Tucson, Az., and Sangamo Inc. of Richmond, Ca.

The California stem cell agency is proposing an operational budget of $17.8 million for the coming fiscal year, an increase of 7.2 percent over estimated spending for the current year ending June 30.

Financial documents (proposed budget and finance report) prepared for tomorrow's CIRM governing board meeting also showed that CIRM hopes to snag "$50 million in new, outside financial commitment for CIRM programs." This would represent the first major effort in recent years by CIRM to solicit private funds. The "draft goal" is in keeping with the agency's move to build a base of non-governmental funding.

Currently it is financed with cash that the state, which is mired in a financial crisis, must borrow. While CIRM's budget is increasing, the general fund budget for the entire state has plummeted from $103 billion in 2007-2008 to $87 billion this year.

The proposed CIRM budget also disclosed the agency will be facing substantial new costs – $1 million annually – for rent beginning in November 2015. CIRM has been operating rent-free since 2005 because of an $18 million recruitment package put together by the city of San Francisco.

The largest item in the proposed budget is salaries and benefits at $11 million, up from a projected $9.3 million for this year. The agency, which is administering $1.3 billion in grants involving hundreds of researchers, projects an increase in staff to 59. The agency currently has 51 employees, according to the finance report.

Outside contracts are the second largest expense at $3.4 million ($3 million this year) with grant reviews, meetings and workshops at $2.2 million(no comparable figure for this year).

By law, the stem cell agency operates under a budget cap of 6 percent of bond proceeds under the terms of Proposition 71, the ballot initiative that created CIRM.

In addition to tomorrow's review, the budget will be examined by the directors Finance Subcommittee April 2 before coming back for final approval in late May.

(Editor's note: An earlier version of this item incorrectly stated that the rent costs would rise to $1 million beginning in 2016. In fact, the increase will begin in November 2015. CIRM has revised the start date.)

The Associated Press news service, whose reports circulate worldwide, has taken the measure of the $3 billion California stem cell agency, declaring that it has produced no cures and that it "faces an uncertain future."

The piece by science writer Alicia Chang asked whether the agency is "still relevant" nearly eight years after it was created by California voters and whether it will exist after the money for new grants runs out in about five years.

She wrote,

"Midway through its mission, with several high-tech labs constructed, but little to show on the medicine front beyond basic research, the California Institute for Regenerative Medicine faces an uncertain future."

Chang's piece carries more weight than those in most publications. The AP is the backbone of news coverage in the United States. Its news feeds appear automatically on hundreds, perhaps thousands of web sites in this country. Her article will also serve as a baseline in the future as other reporters examine the stem cell agency.

Here are excerpts from the piece:

"So what have Californians received for their money so far?

"The most visible investment is the opening of sleek buildings and gleaming labs at a dozen private and public universities built with matching funds. Two years ago, Stanford University unveiled the nation's largest space dedicated to stem cell research - 200,000 square feet that can hold 550 researchers.

"There are no cures yet in the pipeline and CIRM has shifted focus, channeling money to projects with the most promise of yielding near-term results."

Chang wrote,

"Several camps that support stem cell research think taxpayers should not pay another cent given the state's budget woes.

"'It would be so wrong to ask Californians to pony up more money,' said Marcy Darnovsky of the Center for Genetics and Society, a pro-stem cell research group that opposed Proposition 71, the state ballot initiative that formed CIRM."

The article quoted UC Davis stem cell researcher Paul Knoepfler as favoring another bond measure to keep CIRM afloat, although he said he recognizes the average Californian may disagree.

Roger Noll, professor emeritus of economics at Stanford, was quoted as saying that "CIRM's legacy has yet to be written."

"'CIRM spent a lot of money and there's a lot of stuff going on, but it's too early to know whether it was worth it,' Noll said."

Chang concluded with these four paragraphs:

"David Jensen, who runs the blog California Stem Cell Report, said Californians have benefited, but whether it will be worth the $6 billion the state has to pay back remains unclear.

"'The agency's responsibility is now to get the biggest bang for the buck, which is no easy task given the tentative nature of much of the science involved,'" he said in an email.

"Some think CIRM has left a mark whether or not it will exist in the future.

Its 'legacy will be felt in part by the stimulus that it has had on stem cell' research in California, said Fred Gage of the Salk Institute for Biological Studies."

HOUSTON -

Doctors from the Texas Heart Institute at St. Luke's Episcopal Hospital have found that patients with heart failure may be able to repair the damaged areas of the heart with stem cells from the patient's own bone marrow.

Doctors presented the findings at the American College of Cardiologys 61st Annual Scientific Session Saturday.

The results are from a multi-center clinical study that measured the possible benefits of using a patients own bone marrow cells to repair damaged areas of the heart suffering from severe heart failure, a condition that affects millions of Americans.

The study, which was the largest such investigation to date, found that the hearts of the patients receiving bone marrow derived stem cells showed a small but significant increase in the ability to pump oxygenated blood from the left ventricle, the hearts main pumping chamber, to the body.

The expectation is that the study will pave the way for potential new treatment options and will be important to designing and evaluating future clinical trials.

This is exactly the kind of information we need to move forward with the clinical use of stem cell therapy, said Emerson Perin, MD, PhD, Director of Clinical Research for Cardiovascular Medicine at THI, and one of the studys lead investigators.

The bone-marrow derived stem cells are helpful to the injured heart when they are themselves biologically active, added Dr. James T. Willerson, the studys principal investigator and President and Medical Director of THI.

This study moves us one step closer to being able to help patients with severe heart failure who have no other alternatives.

The study was conducted by the Cardiovascular Cell Therapy Research Network, the national consortium to conduct such research funded by the National Institutes of Healths National Heart, Lung, and Blood Institute.

Stem cell, heart heath study

Johannesburg, Mar 25 : Stem cells could repair damage in people with advanced heart disease, a new study has claimed.

According to researchers at a major US cardiology conference, patients with advanced heart disease who received an experimental stem cell therapy showed slightly improved heart function.

The clinical trial involved 92 patients, with an average age of 63, who were picked at random to get either a placebo or a series of injections of their own stem cells, taken from their bone marrow, into damaged areas of their hearts.

The patients all had chronic heart disease, along with either heart failure or angina, and their left ventricles were pumping at less than 45 percent of capacity.

All the participants in the study were ineligible for revascularisation surgery, such as coronary bypass to restore blood flow, because their heart disease was so advanced.

Those who received the stem cell therapy saw a small but significant boost in the heart's ability to pump blood, measuring the increase from the heart's main pumping chamber at 2.7 percent more than placebo patients.

Study authors described the trial as the largest to date to examine stem cell therapy as a route to repairing the heart in patients with chronic ischemic heart disease and left ventricular dysfunction.

"This is the kind of information we need in order to move forward with the clinical use of stem cell therapy," News24 quoted Emerson Perin, the lead investigator from Texas Heart Institute as saying.

Perin's research, which was conducted between 2009 and 2011 across five US sites, was presented at the annual American College of Cardiology Conference in Chicago.

Stem cell therapy `may repair heart damage`

ScienceDaily (Mar. 22, 2012) Researchers at the University of Bonn artificially derive brain stem cells directly from the connective tissue of mice.

Scientists at the Life & Brain Research Center at the University of Bonn, Germany, have succeeded in directly generating brain stem cells from the connective tissue cells of mice. These stem cells can reproduce and be converted into various types of brain cells. To date, only reprogramming in brain cells that were already fully developed or which had only a limited ability to divide was possible. The new reprogramming method presented by the Bonn scientists and submitted for publication in July 2011 now enables derivation of brain stem cells that are still immature and able to undergo practically unlimited division to be extracted from conventional body cells. The results have now been published in the current edition of the journal Cell Stem Cell.

The Japanese stem cell researcher Professor Shinya Yamanaka and his team produced stem cells from the connective tissue cells of mice for the first time in 2006; these cells can differentiate into all types of body cells. These induced pluripotent stem cells (iPS cells) develop via reprogramming into a type of embryonic stage. This result made the scientific community sit up and take notice. If as many stem cells as desired can be produced from conventional body cells, this holds great potential for medical developments and drug research. "Now a team of scientists from the University of Bonn has proven a variant for this method in a mouse model," report Dr. Frank Edenhofer and his team at the Institute of Reconstructive Neurobiology (Director: Dr. Oliver Brstle) of the University of Bonn. Also involved were the epileptologists and the Institute of Human Genetics of the University of Bonn, led by Dr. Markus Nthen, who is also a member of the German Center for Neurodegenerative Diseases.

Edenhofer and his co-workers Marc Thier, Philipp Wrsdrfer and Yenal B. Lakes used connective tissue cells from mice as a starting material. Just as Yamanaka did, they initiated the conversion with a combination of four genes. "We however deliberately targeted the production of neural stem cells or brain stem cells, not pluripotent iPS multipurpose cells," says Edenhofer. These cells are known as somatic or adult stem cells, which can develop into the cells typical of the nervous system, neurons, oligodendrocytes and astrocytes.

The gene "Oct4" is the central control factor

The gene "Oct4" is a crucial control factor. "First, it prepares the connective tissue cell for reprogramming, later, however, Oct4 appears to prevent destabilized cells from becoming brain stem cells" reports the Bonn stem cell researcher. While this factor is switched on during reprogramming of iPS cells over a longer period of time, the Bonn researchers activate the factor with special techniques for only a few days. "If this molecular switch is toggled over a limited period of time, the brain stem cells, which we refer to as induced neural stem cells (iNS cells), can be reached directly," said Edenhofer. "Oct4 activates the process, destabilizes the cells and clears them for the direct reprogramming. However, we still need to analyze the exact mechanism of the cellular conversion."

The scientists at the University of Bonn have thus found a new way to reprogram cells, which is considerably faster and also safer in comparison to the iPS cells and embryonic stem cells. "Since we cut down on the reprogramming of the cells via the embryonic stage, our method is about two to three times faster than the method used to produce iPS cells," stresses Edenhofer. Thus the work involved and the costs are also much lower. In addition, the novel Bonn method is associated with a dramatically lower risk of tumors. As compared to other approaches, the Bonn scientists' method stands out due to the production of neural cells that can be multiplied to a nearly unlimited degree.

Low risk of tumor and unlimited self renewal

A low risk of tumor formation is important because in the distant future, neural cells will replace defective cells of the nervous system. A vision of the various international scientific teams is to eventually create adult stem cells for example from skin or hair root cells, differentiate these further for therapeutic purposes, and then implant them in damaged areas. "But that is still a long way off," says Edenhofer. However, the scientists have a rather urgent need today for a simple way to obtain brain stem cells from the patient to use them to study various neurodegenerative diseases and test drugs in a Petri dish. "Our work could form the basis for providing practically unlimited quantities of the patient's own cells." The current study was initially conducted on mice. "We are now extremely eager to see whether these results can also be applied to humans," says the Bonn scientist.

A new shortcut for stem cell programming

A local toddler with a very rare disease has begun a long recovery in Penn State Hershey Childrens Hospital after chemotherapy and a stem cell transplant.

Chevy Hockenberry, the 23-month-old son of Lance Hockenberry and Melissa Johnson of Mercersburg, suffers from Hurlers syndrome, a rare inherited genetic disorder that if left untreated, causes death within five years.

People with Hurlers syndrome do not produce lysosomal alpha-L-iduronidase, an enzyme that helps break down long chains of sugar molecules. The long sugar chains build up in the body, damage internal organs and eventually lead to death.

The transplant

Chevy was diagnosed with Hurlers in January, but his symptoms started showing up long before that.

He was always sick, Johnson said by phone from Hershey. Chevy was always in and out of the hospital and had developed pneumonia and mild scoliosis.

Once he was diagnosed, the only treatment option for was a stem cell transplant.

Its not curable, Johnson said. But the stem cell transplant stops the progression.

The stem cells came from donated umbilical cords and Chevys parents because they are both carriers of Hurlers.

Chevy had multiple weeks of enzymes infusion followed by nine days of chemotherapy before the stem cell transplant.

CHICAGO (AFP) - Patients with advanced heart disease who received an experimental stem cell therapy showed slight improvements in blood pumping but no change in most of their symptoms, United States researchers said on Saturday.

Study authors described the trial as the largest to date to examine stem cell therapy as a route to repairing the heart in patients with chronic ischemic heart disease and left ventricular dysfunction.

Previous studies have established that the approach is safe in human patients, but none had examined how well it worked on a variety of heart ailments.

The clinical trial involved 92 patients, with an average age of 63, who were picked at random to get either a placebo or a series of injections of their own stem cells, taken from their bone marrow, into damaged areas of their hearts.

Stem cell therapy could repair some heart damage: Study

Public release date: 24-Mar-2012 [ | E-mail | Share ]

Contact: Kristin Wincek kwincek@mhif.org 612-863-0249 Minneapolis Heart Institute Foundation

CHICAGO Cell therapy may present an option for patients with ischemic heart disease to use their own bone marrow cells to repair the damaged areas of their hearts, and may pave the way for future treatment options, according to the FOCUS trial, which will be presented as a late-breaking clinical trial March 24 at the 61st annual American College of Cardiology (ACC) scientific session.

This is the largest study to date to look at stem cell therapy, using a patient's own stem cells, to repair damaged areas of the heart in patients with chronic ischemic heart disease and left ventricular dysfunction. Researchers found that left ventricular ejection fraction (the percentage of blood leaving the heart's main pumping chamber) increased by a small but significant amount (2.7 percent) in patients who received stem cell therapy. The study also revealed that the improvement in ejection fraction correlated with the number of progenitor cells (CD34+ and CD133+) in the bone marrow; and this information will help in evaluating and designing future therapies and trials.

"FOCUS is an incredibly important trial, as it has informed the cell therapy community how to better treat this high-risk patient population, and allows us to enter into an exciting, next generation of stem cell therapy armed with more data," said study investigator Timothy D. Henry, MD, an interventional cardiologist at the Minneapolis Heart Institute (MHI) at Abbott Northwestern Hospital in Minneapolis and director of research with the Minneapolis Heart Institute Foundation.

This multicenter study was conducted by the Cardiovascular Cell Therapy Research Network (CCTRN), which is supported through a research grant from the National Institutes of Health's National, Heart, Lung and Blood Institute (NHLBI), with the goal to evaluate novel stem cell-based treatment strategies for individuals with cardiovascular disease.

FOCUS will be presented at ACC.12 by its lead investigator Emerson C. Perin, MD, PhD, director of clinical research for cardiovascular medicine at the Texas Heart Institute, one of the five sites in the CCTRN. The Minneapolis Heart Institute is another site of the five in the network, and a large number of CCTRN patients were enrolled in Minnesota.

For this study, which took place between April 2009 and April 2011, the five sites randomly selected 92 patients to receive stem cell treatment or placebo. The symptomatic patients, with an average age 63, all had chronic ischemic heart disease and an ejection fraction of less than 45 percent (baseline 34 percent) along with heart failure and/or angina and were no longer candidates for revascularization. "These patients had no other options, as medical management failed to improve their symptoms," explained the study's co-investigator Jay Traverse, MD, an interventionalist cardiologist at the Minneapolis Heart Institute at Abbott Northwestern Hospital and physician researcher with the Minneapolis Heart Institute Foundation.

Bone marrow was aspirated from the patients and processed to obtain just the mononuclear fraction of the marrow. In patients randomly selected to receive stem cell therapy, physicians inserted a catheter into the heart's left ventricle to inject 100 million stem cells in more than 15 sites that showed damage on the electromechanical mapping image of the heart.

"Studies such as these are able to be completed much faster because of the team approach of the network" said Sonia I. Skarlatos, PhD, NHBLI's deputy director of the division of cardiovascular sciences and program director of CCTRN.

Cell therapy using patient's own bone marrow may present option for heart disease

SATURDAY, March 24 (HealthDay News) -- An innovative approach using patients' own bone marrow cells to treat chronic heart failure came up short in terms of effectiveness, researchers report.

Use of stem cell therapy to repair the slow, steady damage done to heart muscle and improve heart function is safe, but has not been shown to improve most measures of heart function, the study authors said.

"For the measures we paid most attention to, we saw no effect, there is no question about that," said researcher Dr. Lemuel Moye, a professor of biostatistics at the University of Texas School of Public Health in Houston.

"Ultimately, this is going to pay off handsomely for individuals and for public health in general, but it's going to take years of work," Moye said. "We are the vanguard looking for new promising lines of research."

While the hoped-for results didn't materialize, there appeared to be a small improvement in some patients, he said. "When we looked at another commonly used measure of heart function called ejection fraction, or the strength of the heart's pumping, that's where all the action was," Moye noted.

It's hard to know which measures of heart function to look at, Moye explained. "We have had some difficulty with that," he said.

Future research will look at other measures of heart function, pay more attention to the characteristics of the cells that are injected and determine which cells are best, he added.

Cardiac cells and other types of specially prepared cells are available now that were not accessible when this study started in 2009, Moye pointed out.

The results of the trial, which was sponsored by the U.S. National Heart, Lung, and Blood Institute, were to be presented Saturday at the American College of Cardiology's annual meeting in Chicago. The report was also published online March 24 in the Journal of the American Medical Association.

For the study, Moye and colleagues worked with 92 patients, average age 63 and mostly male, who had heart failure with and without chest pain. They were randomly assigned to receive either an injection of 100 million bone marrow cells from their own bone marrow, or an inactive placebo. Patients in both groups also received aggressive medical therapy.

Stem-Cell Trial Failed to Treat Heart Failure

CHICAGO - Patients with advanced heart disease who received an experimental stem cell therapy showed slightly improved heart function, researchers said at a major U.S. cardiology conference on Saturday.

The clinical trial involved 92 patients, with an average age of 63, who were picked at random to get either a placebo or a series of injections of their own stem cells, taken from their bone marrow, into damaged areas of their hearts.

The patients all had chronic heart disease, along with either heart failure or angina, and their left ventricles were pumping at less than 45 per cent of capacity.

All the participants in the study were ineligible for revascularization surgery, such as coronary bypass to restore blood flow, because their heart disease was so advanced.

Those who received the stem cell therapy saw a small but significant boost in the heart's ability to pump blood, measuring the increase from the heart's main pumping chamber at 2.7 per cent more than placebo patients.

Study authors described the trial as the largest to date to examine stem cell therapy as a route to repairing the heart in patients with chronic ischemic heart disease and left ventricular dysfunction.

"This is the kind of information we need in order to move forward with the clinical use of stem cell therapy," said lead investigator Emerson Perin, director of clinical research for cardiovascular medicine at the Texas Heart Institute.

Perin's research, which was conducted between 2009 and 2011 across five U.S sites, was presented at the annual American College of Cardiology Conference in Chicago.

The technique involved taking bone marrow samples from the patients and processing the marrow to extract stem cells. Doctors then injected the cells via catheter into the heart's left ventricle.

The injections, comprising some 100 million stem cells in all, were specifically targeted at damaged areas, identified by real-time electromechanical mapping of the heart.
