Are stem cells a veritable fountain of youth? Do they hold the key not only to radiant appearance, but to increased life- & health-span? University of California San Diego stem cell biologist Rob Signer, Ph.D., will outline an intriguing new research paradigm — one in which the focus shifts away from targeting singular disorders like cancer & Alzheimer's, toward addressing a common cause. "The No. 1 risk factor for these conditions is aging," Signer says. "If we can understand & target mechanisms of aging, we should be able to prevent multiple diseases & improve personal & population health."
