Nerve stem cell transplants may help slow the progression of macular degeneration, the most common cause of blindness in the developed world, U.S. researchers said on Monday.
They said putting nerve stem cells from StemCells Inc near the retinas of rats with a form of macular degeneration helped keep the disease from advancing to blindness for several months.
“These cells improve the chemical environment in the back of the eye,” said Ray Lund of the Casey Eye Institute at Oregon Health & Science University in Portland, whose findings were presented at the Society for Neuroscience meeting in Chicago.
Adult stem cells tested for defects before being implanted in the injured spinal cords of mice helped the animals recover with no cancerous side effects, according to new research. In recent years, scientists found that some experimental stem cell therapies can cause cancerous tumors. Pre-screened cells could result in potentially life- saving treatments without such side effects.
These new findings were presented at Neuroscience 2009, the annual meeting of the Society for Neuroscience and the world’s largest source of emerging news about brain science and health. “We tried to identify induced pluripotent stem cells from adult tissue that would be
DaVinci Biosciences LLC, of Costa Mesa, CA, announced today the presentation of their safety and feasibility study demonstrating the administration of autologous bone marrow derived stem cells for the treatment of acute and chronic spinal cord injury at Neuroscience 2009, Society for Neuroscience’s 39th Annual Meeting, to be held at McCormick Convention Center in Chicago, IL. Rafael Gonzalez, Ph.D., Director of Research and Development for DaVinci Biosciences LLC will present the work during the conference on October 20, 2009 and be available to answer questions regarding the study, following his presentation.
“We are excited to share the findings
