摘要:

文题释义:

三维培养:是一种模拟细胞在体内生长的三维微环境的体外培养技术,相对于传统的二维培养,三维培养的细胞增殖分化、基因表达等都更接近于生理状态。
成肝分化:在培养系统中添加一定的细胞生长因子,将间充质干细胞诱导分化成肝细胞样细胞,生成的肝细胞样细胞具有成熟肝细胞的功能如白蛋白分泌、尿素合成等,肝细胞移植可用于肝脏疾病的替代治疗。

摘要
背景:间充质干细胞诱导的成肝细胞样细胞是很有前途的肝再生或肝脏组织工程的种子细胞,传统的二维培养成肝诱导效率低下,越来越多的研究集中在三维培养诱导成肝分化上。
目的:总结间充质干细胞成肝诱导的三维培养模型,重点讨论间充质干细胞成肝分化的表观遗传学调控机制研究进展,为提高间充质干细胞成肝分化的效率提供理论依据。
方法:检索PubMed 数据库及中国知网等数据库收录的相关文献,英文检索词为“mesenchymal stem cells,3D culture,hepatogenic differentiation,hepatocyte-like cells,epigenetics”,中文检索词为“间充质干细胞,三维培养,成肝分化,肝细胞样细胞,表观遗传学”,并结合文献溯源法查找部分文献进行综述分析。
结果与结论:①目前常见的间充质干细胞成肝分化的三维培养模型包括细胞球、生物支架、生物打印、微流控芯片等,它们在诱导成肝分化过程中各有优势和不足;②间充质干细胞成肝分化过程中表观遗传学调控起到关键作用,主要涉及组蛋白修饰、DNA甲基化、非编码RNA的调控等,不同的表观遗传修饰和机制相互作用,共同调节间充质干细胞成肝分化;③在三维培养条件下诱导间充质干细胞成肝分化过程中,表观遗传学修饰尤其是组蛋白乙酰化发挥了重要作用。未来,需要结合表观遗传学优化三维培养策略,提高成肝诱导效率。

Abstract: BACKGROUND: Hepatocyte-like cells induced by mesenchymal stem cells are promising seed cells for liver regeneration or liver tissue engineering. The efficiency of traditional two-dimensional culture for hepatocyte induction is low, and more and more research is focused on three-dimensional culture for inducing hepatocyte differentiation. 
OBJECTIVE: To summarize three-dimensional culture models for the hepatic induction of mesenchymal stem cells, focus on research progress on the epigenetic regulation mechanisms of mesenchymal stem cell hepatogenic differentiation, providing a theoretical basis for improving the differentiation efficiency of mesenchymal stem cells.
METHODS: Relevant articles in the PubMed and other databases such as CNKI were searched, using Chinese and English search terms “mesenchymal stem cell, 3D culture, hepatogenic differentiation, hepatocyte-like cells, epigenetics.” Additionally, the literature tracing method was employed to find some of the literature for a comprehensive review and analysis.
RESULTS AND CONCLUSION: (1) Common three-dimensional culture models for the hepatogenic differentiation of mesenchymal stem cells currently include spheroids, biological scaffolds, bioprinting, and microfluidic chips. Each of these models has its own advantages and disadvantages in the process of inducing hepatogenic differentiation. (2) During the differentiation of mesenchymal stem cells into hepatocyte-like cells, epigenetic regulation plays a key role, primarily involving histone modification, DNA methylation, and the regulation of non-coding RNAs. (3) Under three-dimensional culture conditions, epigenetic modifications, especially histone acetylation, play an important role in promoting the hepatogenic differentiation of mesenchymal stem cells.
