Abstract: Objective To investigate the role of Wnt/β-catenin signaling pathway in the process of adipose-derived stem cells (ADSCs)differentiating into neurons.Methods The third generation of ADSCs were divided into three groups.Neural induction medium was used in induction group and DDK-1 was added into neural induction medium in inhibition group.Normal culture medium was used in control group.Ten days after culture,Real-time PCR and Western blot were used to detect the expressions of NSE,β-catenin and GSK-3βin each group.Results The expressions of NSE and β-catenin were high but the expression of GSK-3 was low in induction group.The expression ofβ-catenin was lower but GSK-3 was higher in inhibition group;the expression of NSE was much lower than that in induction group,but higher than control group.Conclusion The differentiation of ADSCs into neurons is related to activation of Wnt signaling pathway,but Wnt signal pathway is not the only pathway to regulate ADSCs differentiation which may be controlled by different signaling pathways.
