科研领域:
干细胞生物学/再生医学：胚胎干细胞定向分化；组织器官再生。
发育生物学：哺乳动物肝脏和胰腺发育机理。
系统生物学：细胞信号、表观遗传对发育和再生过程中基因网络的调控。
哺乳动物中肝脏及胰腺相互协调在代谢的过程中发挥关键作用。当肝脏和胰腺的细胞出现损伤和功能紊乱时，就会导致许多代谢疾病（如肝病和糖尿病），严重影响健康。因此如何促进肝脏和胰腺的再生是本领域的重要问题。干细胞研究和肝脏、胰腺发育的调控相结合，将更好地解决这一问题。
本实验室长期研究方向主要集中在肝脏及胰腺发育过程中细胞分化，器官建成和再生，主要包括，（1）研究哺乳动物从胚胎发生开始的发育过程中肝实质细胞及内分泌细胞的分化及成熟机制。细胞信号、表观遗传修饰和基因网络协调作用，对这些细胞的分化及成熟过程进行着严格的调控。这些不同层次的调控机制是我们关注的重点。（2）利用获得的肝脏发育过程中的线索指导体外胚胎干细胞分化成成熟的肝实质细胞，用于对肝病进行细胞水平的治疗。（3）将胰腺发育中内分泌细胞分化和成熟过程中获得线索应用于干细胞分化为β细胞的流程，以更好的诱导出有生理功能、成熟的分泌胰岛素的β细胞。（4）通过对肝脏和胰腺发育过程的分子机制研究，结合体外干细胞诱导分化，体外重建有功能的肝脏和胰岛，为再生医疗治疗代谢疾病奠定基础。
