Stem Cells: The Brain's Beginnings

UCTV Video

Fred H. Gage is Professor and Vi and John Adler Chair for Research on Age-Related Neurodegenerative Diseases Laboratory of Genetics

Fred H. Gage, a professor in the Laboratory of Genetics, concentrates on the adult central nervous system and unexpected plasticity and adaptability to environmental stimulation that remains throughout the life of all mammals. His work may lead to methods of replacing or enhancing brain and spinal cord tissues lost or damaged due to Neurodegenerative disease or trauma.

Gage's lab showed that, contrary to accepted dogma, human beings are capable of growing new nerve cells throughout life. Small populations of immature nerve cells are found in the adult mammalian brain, a process called Neurogenesis. Gage is working to understand how these cells can be induced to become mature functioning nerve cells in the adult brain and spinal cord. They showed that environmental enrichment and physical exercise can enhance the growth of new brain cells and they are studying the underlying cellular and molecular mechanisms, that may be harnessed to repair the aged and damaged brain and spinal cord.

About the Series: Grey Matters: Molecules to Mind

During the past decade, there have been dramatic advancements in the brain and cognitive sciences. For the first time, understanding how the brain works has become a scientifically achievable goal.
In this new lecture series, Grey Matters: Molecules to Mind, San Diego's leading Neuroscientists explore the human brain. The first lecture in this series addresses an issue that has often been absent in these discussions: what role do stem cells play in development of the brain?
