    摘要:

    目的:建立长爪沙鼠原代肝细胞分离培养体系。方法:以雄性长爪沙鼠肝细胞为供体,采用组织消化法和Seglen两步灌流法分离肝细胞,以台盼蓝染色检测细胞得率和活率,PAS法鉴定肝细胞,倒置显微镜观察肝细胞形态变化,并使用含有多种细胞因子的培养基维持培养。结果:组织消化法和Seglen两步灌流法平均每只长爪沙鼠肝脏分离获得肝细胞分别为(1.33?.34)?07个、(3.97?.15)?07个,细胞活率分别为(29.4?.05)%、(80.3?.56)%,这两种方法在细胞得率及活率方面存在显著差异。肝细胞内因有大量的糖原颗粒,经PAS法染色后被染成红色。结果表明肝细胞在贴壁后72h内,肝细胞形态发生显著变化。结论:采用胶原酶经肝门静脉灌流分离肝细胞是一种高效获得肝细胞的方法。各种细胞因子有利于维持肝细胞在体外的生长分化,长爪沙鼠原代肝细胞分离培养体系的建立将为肝脏相关疾病研究和防治药物的开发提供技术支持。

    Abstract:

    Objectives: To establish the cultured protocol on Mongolian Gerbil hepatocytes. Method: The hepatocytes were isolated from male Mongolian Gerbil by the methods of tissue digestion and collagenase perfusion. The yield and viability were determined by trypan blue exclusion. The isolated hepatocytes were identified by Periodic acid-Schiff reaction(PAS). The morphology was evaluated with using microscope. Then the medium was repalced with various kinds of cytokines. Results: In sequence of tissue digestion, collagenase perfusion in situ, the hepatocyte’s yield per Mongolian Gerbil was respectively (1.33?.34)?07, (3.97?.15)?07; survival ratio was respectively (29.4?.05)%, (80.3?.56)%. Significant differences were revealed in the yield and viability between the two methods. Numerous glycogenosomes were found in cultured hepatocytes and revealed redness by PAS staining. Significant changes were discovered on morphology after the hepatocytes inoculated in 72 hours. Conclusions: The collagenase perfusion isolation method was economical and high efficiency for separating Mongolian Gerbil hepatocytes. The presence of cytokines in medium could promote the Mongolian Gerbil hepatocyte growth and maintain its function. Successfully establishing the primary cultured protocol of Mongolian Gerbil hepatocytes and it could be used for the reseach on the liver disease and drug exploitation in the future.
