Bone Marrow Stem Cell Release Regulated By Brain's Biological Clock

Source: Mount Sinai Medical Center
Date: February 7, 2008

Summary:

Researchers have discovered that the release of blood stem cells from bone marrow is regulated by the brain through the cyclical human biological clock, via adrenergic signals transmitted by the sympathetic nervous system. These new findings point out that the harvest of stem cells for transplantation may be improved by timing it at the peak of their release.
