Stem Cells Offer New Insight into Helping the Brain Regenerate

Hongjun Song, Ph.D., of the Johns Hopkins School of Medicine, is intrigued about niches in a brain structure called the hippocampus where stem cells live and can give rise to new neurons, a process called neurogenesis. With the support of a 2008 NARSAD Independent Investigator Grant, Dr. Song and team developed a genetic strategy for tracing the life cycle of precursor cells in the brain. What they found was that any single stem cell is capable of both replacing itself and of giving rise to both neurons and glia.
