Abstract
What is the relationship between stem cell aging and organismal aging? Does stem cell aging cause organismal aging or vice versa? Will stem cell aging aggravate age-related diseases? And what is stem cell aging? As suggested herein, hyperstimulation of signal transduction pathways can render cells compensatorily irresponsive. And the hallmark of stem cell aging is poor responsiveness to activating stimuli. On the basis of the hypothesis that insensitivity to stimuli is in part due to hyperactivation of the target of rapamycin (TOR), this article suggests a means of pharmacologic rejuvenation of stem cells and wound-healing cells.Entities:
