文题释义:

淤胆:即胆汁淤积,是由胆汁生成障碍或/和胆汁流动障碍所致的一组疾病共同的临床症状。在瘀胆动物模型中,肝干细胞可以大量增殖。瘀胆血清可能可以为肝干细胞的增殖和分化等提供良好的微环境,促进肝细胞的增殖与分化,被认为是肝干细胞增殖分化的良好微环境。

细胞诱导分化:细胞诱导分化指的是通过一定的方式,利用一定的环境,对细胞进行干预,诱导其向特定的方向发生分化的过程。细胞诱导分化过程中,需要按照实际分化的需求,构建一定的细胞微环境,以更好的引导细胞向特定方向分化。

 

背景:在一定的条件下,骨髓间充质干细胞可发生分化,是肝细胞的重要来源之一,多种因子会对其产生诱导作用。
目的:探讨瘀胆血清在骨髓间充质干细胞向肝细胞分化中的诱导作用。
方法:制备瘀胆动物模型,获得瘀胆血清。将分离的大鼠骨髓间充质干细胞分为3组,分别利用无血清肝细胞培养液、无血清肝细胞培养液+瘀胆血清、无血清肝细胞培养液+正常血清进行培养。

结果与结论:无血清肝细胞培养液+瘀胆血清组的甲胎蛋白阳性表达率、角蛋白18阳性表达率和白蛋白质量浓度均显著高于无血清肝细胞培养液组和无血清肝细胞培养液+正常血清组(P < 0.05)。表明瘀胆血清具有一定的诱导作用,可以诱导骨髓间充质干细胞向肝细胞进行分化。

Abstract:

BACKGROUND: Under certain conditions, bone marrow mesenchymal stem cells can be differentiated into hepatocytes, which are an important source of liver cells. Moreover, multiple factors can be involved in this induced differentiation process.
OBJECTIVE: To investigate the inducible effect of cholestatic serum on the differentiation of bone marrow mesenchymal stem cells into hepatocytes.
METHODS: Cholestatic animal model was prepared in rats to extract cholestatic serum. Bone marrow mesenchymal stem cells isolated from rats were divided into three groups and cultured in serum-free hepatocyte medium, serum-free hepatocyte medium plus cholestatic serum, serum-free hepatocyte medium plus normal serum, respectively.
RESULTS AND CONCLUSION: The positive expression of alpha fetoprotein and keratin 18 and mass concentration of albumin were significantly higher in the serum-free hepatocyte medium plus cholestatic serum group than the other two groups (P < 0.05). These findings indicate that cholestatic serum has a certain inducible role in the differentiation of bone marrow mesenchymal stem cells into hepatocytes.
