"We tested this in laboratory mice to determine if it would repair the brain in a model of stroke, and lead to recovery," said Dr. S. Thomas Carmichael, Professor and Chair of neurology at UCLA. "This study indicated that new brain tissue can be regenerated in what was previously just an inactive brain scar after stroke."
The results suggest that such an approach may someday be a new therapy for stroke in people, said Dr. Tatiana Segura, a former Professor of Chemical and Biomolecular Engineering at UCLA who is now a professor at Duke University. Carmichael and Segura collaborated on the study.
Brain - Capacity - Recovery - Stroke - Diseases
The brain has a limited capacity for recovery after stroke and other diseases. Unlike some other organs in the body, such as the liver or skin, the brain does not regenerate new connections, blood vessels or new tissue structures. Tissue that dies in the brain from stroke is absorbed, leaving a cavity, devoid of blood vessels, neurons or axons, the thin nerve fibers that project from neurons.
To see if healthy tissue surrounding the cavity could be coaxed into healing the stroke injury, Segura engineered...
