Barrow scientists identify new stem cell activity in human brain
Date:9/28/2011

Researchers at Barrow Neurological Institute at St. Joseph's Hospital and Medical Center have identified a new pathway of stem cell activity in the brain that represents potential targets of brain injuries affecting newborns. The recent study, which raises new questions of how the brain evolves, is published in the current issue of Nature, one of the world's most cited scientific journals.

Nader Sanai, MD, director of Barrow's Brain Tumor Research Center, led this study, which is the first developmental study of human neural stem cells in a region of the brain called the subventricular zone, the tissue structure in which brain stem cells reside. Also participating in the study were researchers from University of California San Francisco and the University of Valencia in Spain.

The findings revealed that there is a pathway of young migrating neurons targeting the prefrontal cortex of the human brain in the first few months of life. After the first year of life, the subventricular zone of the brain slows down, tapering production of new brain cells by the time a child is 18-months and then to nearly zero by age two. This revelation settles conflicting prior reports that suggested that human neural stem cell cells remain highly active into adulthood.

"In the first few months of life, we identified streams of newly-generated cells from the subventricular portion of the brain moving toward the frontal cortex," says Dr. Sanai. "The existence of this new pathway, which has no known counterpart in all other studied vertebrates, raises questions about the mechanics of how the human brain develops and has evolved."

Researchers believe this study holds important implications for the understanding of neonatal brain diseases that can cause death or devastating, life-long brain damage. These conditions include germinal matrix hemorrhages, the most common type of brain hemorrhage that occurs in infants; and perinatal hypoxic isch
