摘要: 目的应用小鼠再生肝浸出液体外诱导骨髓间充质干细胞向肝细胞样分化。方法利用2/3肝部分切除术后36h小鼠再生肝组织浸出液定向诱导小鼠骨髓间充质干细胞,在倒置显微镜下观察细胞形态,应用免疫荧光法鉴定细胞性质。结果骨髓间充质干细胞经小鼠再生肝浸出液诱导7d后,呈肝细胞样圆形,1~2周后免疫荧光染色可见细胞表达肝细胞标记物CK8、CK18和清蛋白。结论小鼠再生肝浸出液可诱导骨髓间充质干细胞向肝细胞方向分化。

Abstract: Objective To induce bone marrow mesenchymal stem cells (BMSCs) differentiated into hepatocyte-like cells with rebirth liver tissue lixivium of mouse in vitro.Methods Mouse BMSCs were isolated and directionally induced with rebirth liver tissue lixivium of mouse 36 h after partial hepatectomy (PH). The morphology of cells was observed under an invert microscope, and the characteristics of differentiated cells was identified by immunofluorescence test.Results 7 days after induced by liver lixivium, the spindle shaped BMSCs became round and resembled hepatocyte-like cells. 1~2 weeks later, the differentiated cells expressed albumin, CK8 and CK18, which were known as characteristic markers of the hepatocyte.Conclusion BMSCs of mouse can be differentiated into hepatocyte-like cells under induction of liver tissue lixivium of mouse.
