Team’s Study Could Pave Way to Rejection-Free Adult Stem Cells

Posted: Published on August 6th, 2012

Durham, NC (PRWEB) August 06, 2012 Suppose patient-specific, blood-producing stem cells could be generated in the laboratory, eliminating the need for harvesting bone marrow or finding a matching donor for patients needing a bone marrow transplant? A German research team has generated blood-forming stem cells from pluripotent stem cells in the lab without using animal serum, a technique that could pave the way for production of rejection-free adult stem cells. Researchers Bernhard Schiedlmeier and Hannes Klump led the study, which appears in the current issue of STEM CELLS Translational Medicine. Pluripotent stem cells can develop into various kinds of cells in the body, such as muscle, blood vessels, and bone cells; however, there are several barriers to culturing adult stem cells in a petri dish. It has been especially difficult to generate blood stem cells in the lab without using animal serum, which can carry viruses that interfere with cell reproduction and create other complications. Schiedlmeier and Klump used mouse embryonic stem cells to grow blood-forming stem cells in low-oxygen conditions in the lab without using any serum or supportive cells known as stroma. When they transplanted the blood-forming cells into mice, they found the cells were capable of rebuilding … Continue reading

University of Michigan Informs Interleukin Genetics of Study Results Using the PST Genetic Test in Determining the …

Posted: Published on August 6th, 2012

WALTHAM, Mass.--(BUSINESS WIRE)-- Interleukin Genetics, Inc. (ILIU) announced today that the Company has received top line results from the Periodontal Disease Prevention Study (PDPS) being conducted by the University of Michigan School of Dentistry. The preliminary results indicate that in Low Risk patients, there was no significant difference between two dental preventive visits per year and one preventive visit per year in reducing the percentage of patients who had tooth extractions over the 16 year monitoring period; 13.8% versus 16.4% (p=0.092 ns). In addition, results indicate that in High Risk patients, two preventive visits per year significantly reduced the percentage of patients who had extractions over a 16 year monitoring period compared to one preventive visit per year; 16.9% vs. 22.1% (p=0.002). There was also a positive relationship between number of risk factors and the percentage of patients with extractions (p … Continue reading

Pluristem stem cell therapy saves woman with bone marrow failure

Posted: Published on August 6th, 2012

The share price of Pluristem Therapeutics Ltd. (Nasdaq:PSTI; DAX: PJT: PLTR) is soaring on the TASE, after the company announced that its placental stem cell therapy, Placental eXpanded (PLX), saved the life of a 54-year old Israeli woman suffering from terminal bone marrow failure. This was the second successful treatment of a patient with bone marrow failure in three months, under compassionate use protocols. The PLX therapy was administered at Hadassah Medical Center in Jerusalem. The patient, who was diagnosed with lymphoma cancer, failed to respond to chemotherapy and bone marrow transplants. Intermuscular injection of PLX cells improved the woman's clinical condition and blood count, and she was released from the isolation unit and subsequently discharged from the hospital. "This is a real breakthrough - the woman was in isolation due to low white blood cells and high susceptibility to infections and in addition her red blood cells and platelets were low, leading to a very dangerous and life-threatening situation," said Professor Reuven Or, Director of Bone Marrow Transplantation and Cancer Immunology at Hadassah. "Further, autologous bone marrow transplantation that she received engrafted poorly, and as a last resort, we applied for a compassionate treatment using Pluristem's PLX cells based … Continue reading

Stem Cell Therapy Could Offer New Hope For Head, Mouth Injuries, Defects

Posted: Published on August 6th, 2012

ANN ARBOR In the first human study of its kind, researchers found that using stem cells to re-grow craniofacial tissues mainly bone proved quicker, more effective and less invasive than traditional bone regeneration treatments. Researchers from the University of Michigan School of Dentistry and the Michigan Center for Oral Health Research partnered with Ann Arbor-based Aastrom Biosciences Inc. in the clinical trial, which involved 24 patients who required jawbone reconstruction after tooth removal. Patients either received experimental tissue repair cells or traditional guided bone regeneration therapy. The tissue repair cells, called ixmyelocel-T, are under development at Aastrom, which is a UM spinout company. For a video of the procedure, see: http://youtu.be/lWu_DEJfZVk In patients with jawbone deficiencies who also have missing teeth, it is very difficult to replace the missing teeth so that they look and function naturally, said Darnell Kaigler, principal investigator and assistant professor at the UM School of Dentistry. This technology and approach could potentially be used to restore areas of bone loss so that missing teeth can be replaced with dental implants. William Giannobile, director of the Michigan Center for Oral Health Research and chair of the UM Department of Periodontics and Oral Medicine, is co-principal investigator … Continue reading

Guinea pig hearts beat with human cells

Posted: Published on August 6th, 2012

When transplanted into guinea pig hearts, human heart muscle cells (pictured) can beat in time with resident cells. MEDIMAGE / SPL Damaged skin and liver can often repair themselves, but the heart rarely heals well and heart disease is the world's leading cause of death. Research published today raises hopes for cell therapies, showing that heart muscle cells differentiated from human embryonic stem cells can integrate into existing heart muscle[1]. What we have done is prove that these cells do what working heart muscles do, which is beat in sync with the rest of the heart, says Chuck Murry, a cardiovascular biologist at the University of Washington in Seattle, who co-led the research. It has been difficult to assess cell therapies in animal models because human cells cannot keep up with the heart rates of some small rodents. Cardiomyocytes derived from human embryonic stem (ES) cells typically beat fewer than 150 times a minute. External electrical stimulation can increase that rate, but only up to about 240 beats per minute, says Michael LaFlamme, a cardiovascular biologist at the University of Washington and the other co-leader on the project. Rats and mice have heart rates of around 400 and 600 beats … Continue reading

AP Raiders linebacker Aaron Curry isnt sure when hell be able to get back on the field, but hes pretty sure that stem cell therapy will be the thing that winds up getting him back there. Paul Gutierrez of CSNBayArea.com reports that Curry has received the therapy on both of his knees. Bone marrow from his hips was used in the treatment and Curry told Gutierrez that it is the only thing hes tried that has helped him feel better. Curry is still working out on the side during Raiders practices and said hell only return to practice when hes fully able to help the Raiders. My goal is to get healthy and just go out there and be violent, be fast, be a pain in the offenses butt and whatever I have to do on the defense, do it, Curry said. And do it full speed. I cant do that until my body says its ready. The treatment has been popular with Oakland athletes. Linebacker Rolando McClain said that the treatment helped his legs feel better earlier this offseason and As pitcher Bartolo Colon has credited stem cell treatment on his shoulder with saving his baseball career.
