研究概述
成体干细胞长期存在于多种组织和器官内，顺利获得不断的自我更新和分化，维持组织细胞的新旧更替。干细胞功能的失调可能导致癌症或退行性病变等疾病的发生，但我们对干细胞增殖和分化时细胞的命运抉择等行为的分子调控机制还没有清楚的理解。我们结合相对简单的遗传模式生物果蝇及哺乳动物模型，以肠道干细胞为主要研究对象，研究干细胞自我更新和多个细胞谱系分化过程中命运决定的内源性机制及环境调控机制，及肠上皮细胞的分化和功能调节机制及它们在脑-肠-肠道菌群轴中所扮演的角色。我们的研究将最终为肠道肿瘤、代谢性疾病等肠道相关疾病的防治给予理论依据和试验基础。
Research Description
Adult stem Ezpay(中国)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 Ezpay(中国)s. Dysregulation of stem Ezpay(中国)s is intimately associated with various types of diseases such as cancer and degenerative diseases, but the molecular mechanisms regulating stem Ezpay(中国) fate decisions during self-renewal and Ezpay(中国) lineage differentiation are in general poorly understood. Using intestinal stem Ezpay(中国) systems in both flies and mice, we aim to understand the intrinsic and extrinsic mechanisms underlying stem Ezpay(中国) fate decisions, and the differentiation and functional regulation of intestinal Ezpay(中国)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.
