摘要
胆管树干细胞(biliary tree stem cells, BTSCs)是一类存在于胆管壁上胆周腺内的干细胞,具有分化为成熟肝细胞、胆管上皮细胞及胰腺内分泌细胞等类型细胞的多向分化潜能,在肝损伤治疗、糖尿病救治等方面具有巨大应用前景。本文结合胆管及其相关组织的胚胎发育过程、解剖学特征、BTSCs谱系分布特点及分子标志、体外扩增特性、基础及临床研究现状等,对BTSCs的生物学特性进行阐述,并对其在肝脏和胰腺器官再生中的研究进展和应用前景进行总结和展望。
Biliary tree stem cells(BTSCs)are stem cells located in peribiliary glands on the bile ductal wall.These multipotent stem cells have potentials of differentiation into mature hepatocytes,cholangiocytes and pancreatic endocrine cells.Therefore,they might be used as candidate cell types for treating liver injury and diabetes.This review summaries the biological features of BTSCs,focusing on the embryonic development and anatomical features of the biliary tree and its related tissues,the lineage distribution of BTSCs,cell isolation and purification,in vitro expansion,and in vivo transplantation of BTSCs;and also discusses the prospects of their application in the regeneration of liver and pancreas.
