Research Description

Adult stem 购宝钱包 s reside in many tissues and organs and have the ability to self-renew indefinitely and generate progenies that differentiate and replace aged and damaged 购宝钱包 s. Dysregulation of stem 购宝钱包 s is intimately associated with various types of diseases such as cancer and degenerative diseases, but the molecular mechanisms regulating stem 购宝钱包 fate decisions during self-renewal and 购宝钱包 lineage differentiation are in general poorly understood. Using intestinal stem 购宝钱包 systems in both flies and mice, we aim to understand the intrinsic and extrinsic mechanisms underlying stem 购宝钱包 fate decisions, and the differentiation and functional regulation of intestinal 购宝钱包 s and their roles played in the brain-gut-microbiota axis. Our research should ultimately bring new mechanistic insights into intestinal tumors and other digestive and metabolic diseases and pave the way to new treatments.
