Mini-Gut Organoids: Reconstitution of the Stem Cell Niche
5 Oct 2015
Abstract excerpt
In the adult mammalian body, self-renewal of tissue stem cells is regulated by extracellular niche environments in response to the demands of tissue organization. Intestinal stem cells expressing Lgr5 constantly self-renew in their specific niche at the crypt bottom to maintain rapid turnover of the epithelium. Niche-regulated stem cell self-renewal is perturbed in several mouse genetic models and during human...
