Cholangiocytes are epithelial cells lining the intrahepatic and extrahepatic bile ducts.Cholangiocytes perform key physiological functions in the liver. Bile synthesized by hepatocytes is secreted into bile canaliculi, further stored in the gallbladder, and finally discharged into the duodenum. Due to liver injury, biliary epithelial proliferate in response to endogenous or exogenous signals leading to cholangiopathies, inflammation, fibrosis, and cholangiocarcinoma. Cholangiocytes exhibit anatomical and functional heterogeneity, and understanding such diversified functions will potentially help in finding effective therapies for various cholestatic liver diseases. To perform such functional studies, effective cholangiocyte isolation and culture procedures are needed. This protocol will aid in easy isolation and expansion of cholangiocytes from the liver., [抽象的]胆管细胞是衬在肝内和肝外胆管的上皮细胞。 胆管细胞在肝脏中执行关键的生理功能。肝细胞合成的胆汁分泌到胆管中,进一步储存在胆囊中,最后排入十二指肠。由于肝损伤,胆管上皮响应内源性或外源性信号而增殖,导致胆管病、炎症、纤维化和胆管癌。胆管细胞表现出解剖和功能的异质性,了解这种多样化的功能可能有助于为各种胆汁淤积性肝病寻找有效的治疗方法。为了进行此类功能研究,需要有效的胆管细胞分离和培养程序。该协议将有助于从肝脏中轻松分离和扩展胆管细胞。 [背景]的肝脏在结构和功能多相。它执行重要的功能,如吸收胆固醇;氨基酸、脂质和维生素代谢;以及白蛋白和凝血因子的产生。肝脏由实质细胞和非实质细胞组成,其中肝细胞占主要部分;存在的其他细胞包括胆管上皮细胞(胆管细胞)、星状细胞、肝窦内皮细胞和各种免疫细胞亚群(Zorn,2008)。肝窦内皮细胞在肝窦内的血液和下面的肝细胞之间形成衬里,形成 Disse 的空间。肝小叶是具有中央静脉的功能单位,肝细胞索从中央静脉产生,并被分成将血液从门静脉三联征运送到中央静脉的血窦。门静脉三联征由肝动脉、胆管和门静脉组成。胆管内衬称为胆管细胞的上皮细胞(Malarkey等人,2005 年;Gordillo等人,2015 年),如图 1 所示。胆管上皮主要作为胆汁流动的衬里导管,但它也改变小管胆汁并将胆汁浓缩在胆囊中。胆管上皮是与邻近细胞的“有效沟通者”,可产生参与细胞生长和损伤反应的介质(Chen等,2008)。许多风险因素...
