Abstract (original English)
Human adipose tissue-derived stem cells (hADSCs) have been considered as a promising source for cell therapy of liver diseases due to their accessibility, abundance, and expression of hepatocyte markers. Currently, the important role of certain microRNAs (miRNAs) has been reported during hepatic differentiation of stem cells. However, the combination effect of miRNAs on hepatic differentiation of these cells needs to be more investigated. The present study seeks to determine whether the combination of miRNAs can enhance hepatic differentiation of hADSCs in the absence of any other stimulation. First, lentiviral transduction was used to overexpress miR-122 and silence d let-7f in hADSCs for up to 21 days. Then, hepatic functionality was evaluated by analyzing specific hepatocyte genes and biochemical markers at different time points of differentiation induction. Stable miR-122 overexpression and let-7f silencing together in hADSCs resulted in increased expression of hepatocyte markers including ALB, AFP, CK18, CK19, and HNF4a. In addition, urea and albumin production, immunocytochemistry, and glycogen staining confirmed that the treated cells differentiated toward hepatocyte-like cells. Therefore, our findings demonstrate the possibility of using microRNAs to induce hADSCs into functional hepatocyte-like cells.
