In regenerative medicine, MSCs need to be pluripotent for better results. In this study, the effect of fibrinscaffold on expression of stemness genes was examined. Adipose-derived MSCs were cultured in tissue cultureplates (2D) and 3-dimensional (3D) fibrin scaffolds. The effect of fibrin scaffold on proliferation of adiposederivedMSCs was evaluated by MTT assay. The expression of stemness genes (OCT4 and SOX2) wereevaluated by qRT-PCR, and flow cytometry was done for Nanog protein level. Cultured MSCs on fibrinscaffold were able to proliferate according to data obtained by MTT assay. Expression of OCT4 and SOX2 hada significant increase in cells were cultured in 3D condition compared to 2D condition (P less than 0.05). Also,increased expression of Nanog protein in 3D culture was observed (P less than 0.05). OCT4 and SOX2 in 3Dcondition increased two-fold and three-fold respectively in 2D and 3D conditions. Moreover, expression ofNanog increased 30% more than in 2D condition. Evaluation of important pluripotency regulators such asOCT4, SOX2, and Nanog showed that fibrin scaffolds are useful instruments to maintain stemness of MSCs,which is essential in field of stem cell therapy and regenerative medicine.
