Role of the nervous system in regulating stem cells discoveredStudy led by Mount Sinai School of Medicine may provide new hope for cancer patients and others with compromised immune systems New study by Mount Sinai researchers may lead to improved stem cell therapies for patients with compromised immune systems due to intensive cancer therapy or autoimmune disease. The study is published in this week's issue of Cell. A group, led by Paul Frenette, Associate Professor of Medicine at Mount Sinai School of Medicine, found that the sympathetic--or "fight or flight" branch--of the nervous system plays a critical role in coaxing...
