Abstract (original English)
Human adipose-derived stem cells (hADSCs), widely present in the adult human body, are an emerging and attractive tool for the establishment of stem cell-based therapies for the treatment of liver disease. However, the mechanism underlying hADSCs hepatic differentiation remains to be elucidated. Caveolin-1 (Cav-1), a 21-24 kDa membrane structural protein, is important in liver regeneration and development. In the present study, fluorescence immunocytochemistry and western blotting were used to analyze the expression levels of Cav-1 and evaluate its effects on the hepatic differentiation of hADSCs. The results revealed that primary hADSCs preserved the ability to proliferate and differentiate into hepatocyte-like cells. As demonstrated by semiquantitative reverse transcription-polymerase chain reaction, hepatocyte-inducing factors significantly increased the expression of Cav-1 in a time-dependent manner, as indicated by increased expression levels of the albumin (ALB) and α-fetoprotein (AFP) markers. In addition the expression levels of ALB and HNF1A significantly decreased following small interfering RNA-mediated knockdown of Cav-1. The mitogen-activated protein kinase (MAPK) signaling pathway was activated during hepatic differentiation and inhibited following Cav-1 knockdown. These results suggested that Cav-1 may regulate the hepatocyte-like differentiation of hADSCs by mod
