Methods of bone marrow mesenchymal stem cells differentiating into hepatocytes and the underlying mechanisms / 中国组织工程研究

ABSTRACT

BACKGROUND:A number of studies have shown that there are many inducible methods by which bone marrow mesenchymal stem cel s 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 cel s 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 cel s into hepatocytes published between 2004 and 2015. The key words were“hepatocyte (-like) cel s, bone marrow mesenchymal stem cel s, differentiation”in Chinese and English, respectively. Final y, 62 articles were included in result analysis. RESULTS AND CONCLUSION:There are many programs for hepatic differentiation of bone marrow mesenchymal stem cel s, but the specific molecular mechanism is stil 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 cel s that can be induced to differentiate into mature hepatocytes provide an ideal cel ular source for hepatocyte transplantation and artificial liver, which is proposed to be a new strategy for clinical treatment of end-stage liver disease.
