Almost all adult tissues require periodic replenishments and damage repairs. A group of slowdividing cells, called stem cells, nestled within each tissue carries out thejob throughout the lifespan of an organism. Stem cells have a unique capabilityof undergoing regulated asymmetric divisions resulting in self-renewal and generationof a progeny cell with predetermined cell-fates (Friedenstein et al., …
