Activation of the Wnt signaling pathway enhanced hUCMSCs differentiation. a Western blotting was applied to detect the changes in the levels of β-catenin, c-Myc, p63, CK19, and PCNA proteins. b Statistical analysis of a results. c The differentiation degree of hUCMSCs was evaluated by cell morphology under optical microscope (scale: 100 μm). d Statistical analysis on the ratio of cells with round or small polygonal morphology displayed in c; *P < 0.05, **P < 0.01 vs. control (n = 3)
