A new weapon against stroke

Posted: Published on July 24th, 2013

Public release date: 23-Jul-2013 [ | E-mail | Share ] Contact: Charles Casey charles.casey@ucdmc.ucdavis.edu 916-734-9048 University of California - Davis Health System (SACRAMENTO, Calif.) -- One of regenerative medicine's greatest goals is to develop new treatments for stroke. So far, stem cell research for the disease has focused on developing therapeutic neurons the primary movers of electrical impulses in the brain to repair tissue damaged when oxygen to the brain is limited by a blood clot or break in a vessel. New UC Davis research, however, shows that other cells may be better suited for the task. Published July 23 in the journal Nature Communications, the large, collaborative study found that astrocytes neural cells that transport key nutrients and form the blood-brain barrier can protect brain tissue and reduce disability due to stroke and other ischemic brain disorders. "Astrocytes are often considered just 'housekeeping' cells because of their supportive roles to neurons, but they're actually much more sophisticated," said Wenbin Deng, associate professor of biochemistry and molecular medicine at UC Davis and senior author of the study. "They are critical to several brain functions and are believed to protect neurons from injury and death. They are not excitable cells like … Continue reading

Students who had their genome tested as part of a groundbreaking medical school course on personalized medicine improved their knowledge of the class materials by an average of 31 percent compared with those who didn't undergo the testing, according to a study by researchers at the Stanford University School of Medicine. While the sample size was small 23 students sent their saliva to a commercial genetics testing company; eight did not the results may encourage educators to consider this approach in the future, the authors said. "These results indicate that learning principles of human genetics is more powerful, and learning is more sustained, when exploring your own data," said Keyan Salari, MD, PhD, a former Stanford student who initially proposed the course, called "Genomics and Personalized Medicine." Salari, who is the lead author of the study, is now a urology resident at the Massachusetts General Hospital in Boston. The study will be published July 23 in PLOS ONE.

Magnetised carriers help steer stem cells to therapy sites

Posted: Published on July 23rd, 2013

23 July 2013 Magnets could be a tool for directing stem cells to treat conditions such as heart or vascular disease. By feeding stem cells particles made of magnetised iron oxide, scientists at Emory University and the Georgia Institute of Technology believe they can then use magnets to attract the cells to a particular location in the body after intravenous injection. The results are published online in the journal Small and will appear in an upcoming issue. The paper was a result of collaboration between the laboratories of W. Robert Taylor of Emory, and Gang Bao of Georgia Tech. Taylor is professor of medicine and biomedical engineering and Bao is professor in the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University. The study used mesenchymal stem cells that can be obtained from adult tissues such as bone marrow or fat and are capable of becoming bone, fat and cartilage cells, but not other types of cell such as muscle or brain. They secrete a variety of nourishing and anti-inflammatory factors, which could make them valuable tools for treating conditions such as cardiovascular disease or autoimmune disorders. Magnetized iron oxide nanoparticles are already US Food and … Continue reading

De Leon: Medical Tourism and the Future of Stem Cell Therapy (Part 2)

Posted: Published on July 23rd, 2013

LAST week, we discussed the potential of medical tourism in the country which will also provide opportunities for destinations like Baguio once tapped, and subject to competitive and international standards and government/ regulatory requirements. So much has been written and reported about Stem Cell Therapy including its extraordinary promises that research holds for the treatment of a wide range of diseases and conditions. This week, lets delve deeper. What is Stem Cell Therapy? Cell Therapy has been interchangeably called many names such as cellular therapy, fresh cell therapy, live cell therapy, glandular therapy, or xenograph or xenotransplant therapy. The International Society for Stem Cell Research (ISSCR) describes stem cell therapy as a treatment that uses stem cells, or cells that come from stem cells, to replace or to repair a patients cells or tissues that are damaged. The stem cells might be put into the blood, or transplanted into the damaged tissue directly, or even recruited from the patients own tissues for self-repair. Stem Cells have been differentiated based on where in the body or what stage in development they come from. ISCCR has enumerated them as follows (source:www.isscr.org): 1. Adult Stem Cells or Tissue-specific Stem Cells. Many adult tissues … Continue reading

Future blindness cure? Stem cell success in lab

Posted: Published on July 23rd, 2013

Featured Article Academic Journal Main Category: Eye Health / Blindness Also Included In: Stem Cell Research Article Date: 22 Jul 2013 - 7:00 PDT Current ratings for: Future blindness cure? Stem cell success in lab 3.5 (6 votes) Scientists are one step closer to curing blindness, after they carried out the first successful transplant of light-sensitive photoreceptor cells from a synthetic retina that was grown from embryonic stem cells. Researchers from University College London (UCL) and Moorfields Eye Hospital in the UK, transplanted the photoreceptor cells in to night-blind mice and found that the cells developed normally. The cells integrated into the existing retina in the mice and formed the required nerve connections that transmit visual information to the brain. The study, published in the journal Nature Biotechnology, shows embryonic stem cells could potentially be used to provide an "unlimited supply of healthy photoreceptors for retinal cell transplantations to treat blindness in humans." Photoreceptors are light-sensitive nerve cells found in the retina of the eye. There are two types of photoreceptors - rods and cones. The cones provide the eye's color sensitivity. The rods are not sensitive to color, but are more sensitive to light than the cones and are … Continue reading

Light-Detecting Retina Cells Made from Stem Cells

Posted: Published on July 23rd, 2013

Scientists turn embryonic stem cells into photoreceptors that can integrate into a live retina. Transplanted photoreceptors derived from embryonic stem cells (green) integrate into the damaged retina of an adult mouse and touch the next neuron in the retinal circuit (red). Scientists in the U.K. have produced rod-like photoreceptors from embryonic stem cells, and successfully transplanted them into the retinas of mice. The work suggests that embryonic stem cells could perhaps one day be used as a treatment for patients who have lost their vision to retinitis pigmentosa, macular degeneration, or other degenerative conditions in which the light-detecting rods and cones of the retina die over time. Currently, there are few treatment options for these conditions; electronic implanted devices are available for some patients in some countries, but their efficacy is limited (see A Second Artificial Retina Option for the E.U. and What Its Like to See Again with an Artificial Retina).The new work,reported in Nature Biotechnology on Sunday, offers hope for a more effective, comprehensive treatment. The researchers used a new method for growing embryonic stem cells that enables them to turn into immature eye cells and self-organize into three-dimensional structures similar to those seen in a developing retina … Continue reading
