Activation of the Wnt signaling pathway promoted the generation of granulation tissues. a HE staining demonstrated the collagen fiber deposition and changes in capillaries in the granulation tissues (scale: 100 μm). b Statistical analysis of a results. c TUNEL staining detected cell apoptosis at the wound (scale: 50 μm). d Statistical analysis of c results (n = 3); *P < 0.05, **P < 0.01
