文题释义:
Notch信号通路:
Notch基因编码一类高度保守的细胞表面受体,它们调节从海胆到人等多种生物细胞的发育。Notch信号影响细胞正常形态发生的多个过程,包括多能祖细胞的分化、细胞凋亡、细胞增殖及细胞边界的形成。Notch基因位点突变引起的表型改变,表明Notch信号作用的多样性。
miR-122:是一种专一表达于肝脏的miRNA,在生理状态下参与肝细胞发育、肝细胞表型、分化代谢,以及肝细胞应急应答等基本生命活动过程。在病理状态下,miR-122有促进HCV复制和翻译的作用,还可促进肿瘤细胞的凋亡,在肝细胞癌发生、发展过程中发挥抑癌基因样作用。

 

摘要
背景:
已有多项研究证明骨髓间充质干细胞可以跨胚层分化为肝细胞,其向肝细胞定向诱导分化的方案很多,但其具体的分子机制目前尚不清楚。
目的:综述骨髓间充质干细胞诱导分化为肝细胞的方案及分化机制。
方法:检索CNKI数据库、维普、万方和PubMed数据库2004至 2015 年期间关于骨髓间充质干细胞向肝细胞分化的文章。检索词分别为“肝细胞(肝样细胞),骨髓间充质干细胞,诱导分化”和“hepatocyte(-like) cells,bone marrow mesenchymal stem cells,differentiation”。最后选择62篇文章纳入结果分析。
结果与结论:骨髓间充质干细胞诱导分化为肝细胞的方案很多,但其具体的分化机制仍不甚清楚,目前国内外研究较多的主要有Notch信号通路、Wnt/β-catenin 信号通路、P38信号通路、miR-122及钙离子的影响等;骨髓间充质干细胞定向分化的成熟肝细胞为肝细胞移植和人工肝提供了理想的细胞来源,从而使肝细胞移植和人工肝运用于临床治疗终末期肝病提供了新的策略。

Abstract:

BACKGROUND: A number of studies have shown that there are many inducible methods by which bone marrow mesenchymal stem cells can differentiate into hepatocytes, but the specific molecular mechanism is unclear yet.
OBJECTIVE: To review the programs and underlying mechanisms by which bone marrow mesenchymal stem cells differentiate into hepatocytes.
METHODS: A computer-based online search of CNKI, VIP, WanFang and PubMed databases was performed to retrieve articles about directional differentiation of bone marrow mesenchymal stem cells into hepatocytes published between 2004 and 2015. The key words were “hepatocyte (-like) cells, bone marrow mesenchymal stem cells, differentiation” in Chinese and English, respectively. Finally, 62 articles were included in result analysis.
RESULTS AND CONCLUSION: There are many programs for hepatic differentiation of bone marrow mesenchymal stem cells, but the specific molecular mechanism is still unclear. Many studies mainly focus on Notch signaling pathway, Wnt/β-catenin signaling pathway, P38 signal pathway, miR-122 and effect of calcium ions. Bone marrow mesenchymal stem cells that can be induced to differentiate into mature hepatocytes provide an ideal cellular source for hepatocyte transplantation and artificial liver, which is proposed to be a new strategy for clinical treatment of end-stage liver disease.
