实验室研究领域及内容:

目前实验室利用果蝇为模式动物，对肠道干细胞的多功能分化进行深入研究，以期理解干细胞分化的内在生理逻辑和分子基础，以达到对癌症以分化为导向的转化医学治疗。主要研究内容为：1）肠道表皮干细胞数目的决定机制；2）肠道表皮干细胞位置的决定机制；3）肠道干细胞分化过程中Notch信号激活强弱的控制机制；4)肠道干细胞多功能分化的子代细胞比例控制机制。文章发表在Science,DevelopmentalCell，NatureCommunications，The Journal ofCell Biology,CellReports，Development,CommunicationsBiology等国际著名杂志。
