StemCell Therapy

Freeport, Grand Bahama (PRWEB) December 18, 2014

Okyanos, the leader in cell therapy, announced the expansion of its medical team to accommodate the growing demand for cell therapy to treat patients with chronic unmet needs for which adult stem cell therapy using cells from a persons own fat (adipose) tissue has been found to be safe and efficacious. Led by a prestigious team of U.S.-licensed physicians and nursing staff, the team includes Dr. Todd Malan, Chief Cell Therapy Officer and pioneer of adipose-derived stem cell therapy, and is joined by Dr. Matthew Mick, Cardiologist, FACC, Fellowship at Cleveland Clinic.

We are very pleased to have such a competent and highly regarded aggregate of expertise, said Okyanos CEO Matt Feshbach. Our team is comprised of leaders in their respective fields, each of whom is committed to bringing about a new standard of care and better quality of life to our patients.

Todd Malan, MD, serves as the Chief Cell Therapy Officer and General Surgeon at Okyanos, overseeing the fat-harvesting and stem cell isolation step of the Okyanos cell therapy process. A pioneer of fat-derived stem cell therapies, he became the first physician in the U.S. to utilize stem cells from fat for soft tissue reconstruction in October 2009, combining water-assisted fat-harvesting, fat transfer and adult stem cell technologies.

Matthew J. Mick, MD, is a triple board-certified interventional cardiologist. After attending the Indiana University School of Medicine, Dr. Mick completed his Cardiovascular Disease and Interventional Fellowships at the Cleveland Clinic Foundation. Dr. Mick participated as Principal Investigator and Co-Investigator in more than 20 cardiac clinical trials. He was a leader in developing trans-radial cardiac catheterization and holds several patents for cardiac catheters. Dr. Mick has performed over 15,000 diagnostic procedures in his 22 years of practice.

As the Director of Nursing managing a medical team which now numbers 10, Gretchen Dezelick oversees all of the clinical operations and maintains the superior cleanliness and safety standards that help make Okyanos a center of excellence. With more than 25 years of nursing experience progressing from bedside nursing to administrative and management positions in a variety of healthcare settings, Gretchen was a Certified Critical Care Nurse (CCRN) for more than 20 years and has been a Certified Peri-Operative Nurse (CNOR) for more than three years as well as being a Licensed Health Care Risk Manager (LHCRM).

Okyanos is also very proud to include several Bahamian medical staff such as Anesthesiologist Dr. Vincent Burton, Fellow of the Royal College of Anaesthetists, UK (FRCA), a Certified Critical Care Nurse, cardiology tech, sonographer, surgical scrub tech and a facilities tech, to deliver well-rounded expert patient care. The team also includes a Certified Cardiovascular Nurse, a BSN RN and a cardiovascular tech, providing more than 88 years of combined experience.

Okyanos follows the treatment guidelines laid out in clinical trials such as PRECISE and others which have demonstrated positive results from adult stem cell therapy. Okyanos cell therapy is performed in their newly constructed surgery center built to U.S. surgical standards and which also includes a state-of-the-art Phillips cath lab.

Adult stem cell therapy has emerged as a new treatment alternative for those who are restricted in activities they can no longer do but are determined to live a more normal life. Okyanos cell therapy uses a unique blend of adult stem cells derived from a patients own fat tissue, thereby helping the bodys own natural biology to heal itself.

Just 50 miles from US shore, Okyanos cell therapy is available to patients with severe heart disease including coronary artery disease (CAD) and congestive heart failure (CHF) as well as patients with autoimmune diseases, tissue ischemia, neurological and orthopedic conditions.

PHILADELPHIA As the main component of connective tissue in the body, fibroblasts are the most common type of cell. Taking advantage of that ready availability, scientists from the Perelman School of Medicine at the University of Pennsylvania, the Wistar Institute, Boston University School of Medicine, and New Jersey Institute of Technology have discovered a way to repurpose fibroblasts into functional melanocytes, the body's pigment-producing cells. The technique has immediate and important implications for developing new cell-based treatments for skin diseases such as vitiligo, as well as new screening strategies for melanoma. The work was published this week in Nature Communications.

The new technique cuts out a cellular middleman. Study senior author Xiaowei George Xu, MD, PhD, an associate professor of Pathology and Laboratory Medicine, explains, "Through direct reprogramming, we do not have to go through the pluripotent stem cell stage, but directly convert fibroblasts to melanocytes. So these cells do not have tumorigenicity."

Changing a cell from one type to another is hardly unusual. Nature does it all the time, most notably as cells divide and differentiate themselves into various types as an organism grows from an embryo into a fully-functional being. With stem cell therapies, medicine is learning how to tap into such cell specialization for new clinical treatments. But controlling and directing the process is challenging. It is difficult to identify the specific transcription factors needed to create a desired cell type. Also, the necessary process of first changing a cell into an induced pluripotent stem cell (iPSC) capable of differentiation, and then into the desired type, can inadvertently create tumors.

Xu and his colleagues began by conducting an extensive literature search to identify 10 specific cell transcription factors important for melanocyte development. They then performed a transcription factor screening assay and found three transcription factors out of those 10 that are required for melanocytes: SOX10, MITF, and PAX3, a combination dubbed SMP3.

"We did a huge amount of work," says Xu. "We eliminated all the combinations of the other transcription factors and found that these three are essential."

The researchers first tested the SMP3 combination in mouse embryonic fibroblasts, which then quickly displayed melanocytic markers. Their next step used a human-derived SMP3 combination in human fetal dermal cells, and again melanocytes (human-induced melanocytes, or hiMels) rapidly appeared. Further testing confirmed that these hiMels indeed functioned as normal melanocytes, not only in cell culture but also in whole animals, using a hair-patch assay, in which the hiMels generated melanin pigment. The hiMels proved to be functionally identical in every respect to normal melanocytes.

Xu and his colleagues anticipate using their new technique in the treatment of a wide variety of skin diseases, particularly those such as vitiligo for which cell-based therapies are the best and most efficient approach.

The method could also provide a new way to study melanoma. By generating melanocytes from the fibroblasts of melanoma patients, Xu explains, "we can screen not only to find why these patients easily develop melanoma, but possibly use their cells to screen for small compounds that can prevent melanoma from happening."

Perhaps most significantly, say the researchers, is the far greater number of fibroblasts available in the body for reprogramming compared to tissue-specific adult stem cells, which makes this new technique well-suited for other cell-based treatments.

The research was supported by the National Institutes of Health (R01-AR054593, P30-AR057217)

Consider the relationship between an air traffic controller and a pilot. The pilot gets the passengers to their destination, but the air traffic controller decides when the plane can take off and when it must wait. The same relationship plays out at the cellular level in animals, including humans. A region of an animal's genome -- the controller -- directs when a particular gene -- the pilot -- can perform its prescribed function.

A new study by cell and systems biologists at the University of Toronto (U of T) investigating stem cells in mice shows, for the first time, an instance of such a relationship between the Sox2 gene which is critical for early development, and a region elsewhere on the genome that effectively regulates its activity. The discovery could mean a significant advance in the emerging field of human regenerative medicine, as the Sox2 gene is essential for maintaining embryonic stem cells that can develop into any cell type of a mature animal.

"We studied how the Sox2 gene is turned on in mice, and found the region of the genome that is needed to turn the gene on in embryonic stem cells," said Professor Jennifer Mitchell of U of T's Department of Cell and Systems Biology, lead invesigator of a study published in the December 15 issue of Genes & Development.

"Like the gene itself, this region of the genome enables these stem cells to maintain their ability to become any type of cell, a property known as pluripotency. We named the region of the genome that we discovered the Sox2 control region, or SCR," said Mitchell.

Since the sequencing of the human genome was completed in 2003, researchers have been trying to figure out which parts of the genome made some people more likely to develop certain diseases. They have found that the answers are more often in the regions of the human genome that turn genes on and off.

"If we want to understand how genes are turned on and off, we need to know where the sequences that perform this function are located in the genome," said Mitchell. "The parts of the human genome linked to complex diseases such as heart disease, cancer and neurological disorders can often be far away from the genes they regulate, so it can be dificult to figure out which gene is being affected and ultimately causing the disease."

It was previously thought that regions much closer to the Sox2 gene were the ones that turned it on in embryonic stem cells. Mitchell and her colleagues eliminated this possibility when they deleted these nearby regions in the genome of mice and found there was no impact on the gene's ability to be turned on in embryonic stem cells.

"We then focused on the region we've since named the SCR as my work had shown that it can contact the Sox2 gene from its location 100,000 base pairs away," said study lead author Harry Zhou, a former graduate student in Mitchell's lab, now a student at U of T's Faculty of Medicine. "To contact the gene, the DNA makes a loop that brings the SCR close to the gene itself only in embryonic stem cells. Once we had a good idea that this region could be acting on the Sox2 gene, we removed the region from the genome and monitored the effect on Sox2."

The researchers discovered that this region is required to both turn Sox2 on, and for the embryonic stem cells to maintain their characteristic appearance and ability to differentiate into all the cell types of the adult organism.

"Just as deletion of the Sox2 gene causes the very early embryo to die, it is likely that an abnormality in the regulatory region would also cause early embryonic death before any of the organs have even formed," said Mitchell. "It is possible that the formation of the loop needed to make contact with the Sox2 gene is an important final step in the process by which researchers practicing regenerative medicine can generate pluripotent cells from adult cells."

PARIS --(BUSINESS WIRE)-- 13.10.2014 --

Stem cells hold great promise for treating a variety of human diseases and injuries. Basic and translational stem cell research is among the most competitive fields in the life sciences. We have co-organized the first Bridging Biomedical Worlds conference of our new series of international scientific meetings: Turning Obstacles into Opportunities for Stem Cell Therapy.

The goal of this conference is to promote progress in the translation of basic stem cell research into stem cell therapies. To do this, presentations will highlight diverse areas of on-going stem cell biology research. In addition, panelists will discuss obstacles to translation and the associated risks and ethical controversies. These panels will provide a means to accelerate communication and cooperation among researchers, bioengineers, clinicians and industry scientists, and will explore ways to implement international policies, regulations and guidelines to ensure the development of safe and effective stem cell therapies worldwide. Participants will hear about the latest basic and translational stem cell research from more than 20 distinguished speakers from China, Japan, Europe and theUnited States.

This conference held in Beijing, China, October 13-15, 2014 is co-organized by the Fondation IPSEN, AAAS/Science and AAAS/Science Translational Medicine, in association withFred Gage (Salk Institute for Biological Studies) and Qi Zhou (Institute of Zoology, Chinese Academy of Sciences).

About AAAS/Science The American Association for the Advancement of Science (AAAS) is the worlds largest general scientific society and publisher of the journal Science (www.sciencemag.org) as well as Science Translational Medicine (www.sciencetranslationalmedicine.org) and Science Signaling (www.sciencesignaling.org). AAAS was founded in 1848, and includes some 261 affiliated societies and academies of science, serving 10 million individuals.Sciencehas the largest paid circulation of any peer-reviewed general science journal in the world, with an estimated total readership of 1 million.

TORONTO A Canadian-led international team of researchers has begun solving the mystery of just how a specialized cell taken from a persons skin is reprogrammed into an embryonic-like stem cell, from which virtually any other cell type in the body can be generated.

The research is being touted as a breakthrough in regenerative medicine that will allow scientists to one day harness stem cells to treat or even cure a host of conditions, from blindness and Parkinsons disease to diabetes and spinal cord injuries.

Besides creating the reprogramming roadmap, the scientists also identified a new type of stem cell, called an F-class stem cell due to its fuzzy appearance. Their work is detailed in five papers published Wednesday in the prestigious journals Nature and Nature Communications.

Dr. Andras Nagy, a senior scientist at Mount Sinai Hospital in Toronto, led the team of 50 researchers from Canada, the Netherlands, South Korea and Australia, which spent four years analyzing and cataloguing the day-by-day process that occurs in stem cell reprogramming.

The work builds on the 2006-2007 papers by Shinya Yamanaka, who showed that adult skin cells could be turned into embryonic-like, or pluripotent, stem cells through genetic manipulation, a discovery that garnered the Japanese scientist the Nobel Prize in 2012.

Nagy likened the roughly 21-day process to complete that transformation to a black box, so called because scientists did not know what went on within the cells as they morphed from one cell type into the other.

It was just like a black box, Nagy said Wednesday, following a briefing at the hospital. You start with a skin cell, you arrive at a stem cell but we had no idea what was happening inside the cell.

Nagys team set about cataloguing the changes as they occurred by removing cells from culture dishes at set points during the three-week period, then analyzing such cellular material as DNA and proteins present at that moment.

The result is a database that will be available to scientists around the world, which the team hopes will spur new research to advance the field of stem cell-based regenerative medicine.

Co-author Ian Rogers, a scientist in Nagys lab, said the database will allow researchers to identify various properties of the developing stem cells, which could mean improving their ability to treat or cure disease.
