CRI Scientists Discover Estrogen Promotion of Stem Cell Self-Renewal

Jan. 22, 2014 — Scientists have known for years that stem cells in male and female sexual organs are regulated differently by their respective hormones. In a surprising discovery, researchers at the Children’s Medical Center Research Institute at UT Southwestern and Baylor College of Medicine have found that stem cells in the blood-forming system — which is similar in both sexes — also are regulated differently by hormones, with estrogen proving to be an especially prolific promoter of stem cell self-renewal.
