项目摘要

We aimed to develop the methods of producing a large number of small hepatocytes(SHs), hepatic progenitor cells, and to establish the methods of hepatic organoid formation in vitro. In addition, we examined how cells and tissues could be transplanted into liver. Unlike mature hepatocytes the growth of rat SHs was regulated by Follistatin/Activin system. Although oval cells, hepatic stem cells, differentiated into hepatocytes via SHs, they could not completely mature. The transplanted hepatic stem/progenitor cells could not survive for a long term in the recipient liver and disappeared by cellular senescence. Thus, the role of hepatic stem/progenitor cells in severe liver failure may be to compensate for the lost hepatic functions transiently. To use the model of hepatic sinusoids constituting rat SHs, stellate cells, and endothelial cells, we clarified that quiescent stellate cells might regulate the capillary formation of endothelial cells and maturation of SHs.
我们旨在开发产生大量小肝细胞(SHS),肝祖细胞的方法,并在体外建立肝癌形成的方法。此外,我们研究了如何将细胞和组织移植到肝脏中。与成熟的肝细胞不同,大鼠SHS的生长受卵泡蛋白/激活素系统调节。尽管椭圆形细胞(肝干细胞)通过SHS分化为肝细胞,但它们无法完全成熟。移植的肝干/祖细胞在受体肝脏中无法长期生存,并因细胞衰老而消失。因此,肝干/祖细胞在严重肝衰竭中的作用可能是瞬时补偿肝功能丧失。为了使用构成大鼠SHS,星状细胞和内皮细胞的肝弦模型,我们澄清说,静态的星状细胞可能调节内皮细胞的毛细血管形成和SHS的成熟。
