The enhancement of differentiating adipose derived mesenchymal stem cells toward hepatocyte like cells using gelatin cryogel scaffold

Based on the results of flowcytometry, the isolated cells were positive for hMSC specific markers and negative for hematopoietic markers. Further, the multipotency of these cells was confirmed by adipogenic and osteogenic differentiation and the highly porous structure of scaffolds was characterized by SEM images. Biocompatibility was observed in the fabricated gelatin scaffolds and the adhesion and proliferation of hADSCs were promoted without any cytotoxicity effects. In addition, compared to 2D TCPS, the fabricated scaffolds provided more appropriate microenvironment resulting in promoting the differentiation of hADSCs toward hepatocyte-like cells with higher expression of hepatocyte-specific markers and appropriate functional characteristics such as increased levels of urea biosynthesis and glycogen storage. Finally, the created 3D gelatin scaffold could provide an appropriate matrix for hepatogenic differentiation of hADSCs, which could be considered for liver tissue engineering applications.
