In the recent study, a team led by Dr. Mike Modo of the Institute of Psychiatry, King’s College London investigated replacing stroke-damaged tissue in rats with new tissue from stem cells. Strokes, caused by blockages in brain blood vessels lead to dead areas of brain tissue. Past studies have looked at replacing this dead tissue with stem cells, which would grow into new brain tissue. However, they have met with little success.
The new study, though, shows such growth is possible; the cells just need a scaffolding to grow. In past studies, the cells migrated to other areas of the brain, making them essentially useless in fixing the problem. In the new study researchers attach them to a tiny scaffold made of a biodegradable polymer called PLGA, and coated this scaffolding in neural stem cells. The result is that the damaged brain tissue is regrown successfully in just 7 days. The technique has a strong likelihood of being able to…
