Inhibiting Key Nutrient Sensing Pathway May Reverse Age-Related Stem-Cell Loss

Researchers from Stanford University, the Buck Institute, Columbia University, and the USCF School of Medicine, report that TOR, a nutrient sensing pathway which is critical to the aging process, drives the loss of adult stem cells. Treating mice with the TOR-inhibitor rapamycin prevented this loss and could reverse age-related loss of stem cells in mouse trachea, say the scientists who published their study (“ mTORC1 Activation during Repeated Regeneration Impairs Somatic Stem C
