Function of stem cells in blood-forming system is regulated by estrogen, says study

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 (CRI) 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.

Researchers report three-fold increase in use of minimally invasive surgery for pancreatic disease

Researchers at University of California, San Diego School of Medicine report a three-fold increase in the use of minimally invasive surgery across the nation for patients with pancreatic disease. Although adaptation of MIS for this difficult-to-reach gland is recent, the growing trend points to improved patient outcomes, such as reduced bleeding and infections. Now published online, the paper will appear in the March print edition of JAMA Surgery.
