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
