Therapeutic potential of umbilical cord mesenchymal stem cells with Wnt/β-catenin signaling pathway pre-activated for the treatment of diabetic wounds.

The pathogenesis of diabetes mellitus wounds is complicate, and there lacks effective treatment strategies. Mesenchymal stem cells can promote wound healing. Compared with bone marrow mesenchymal stem cells, umbilical cord mesenchymal stem cells have obvious advantages in biological property. Wnts are potent regulatory molecules for stem cell turnover and skin regeneration, while Wnt signaling is not well activated in diabetic wounds. Umbilical cord mesenchymal stem cells with Wnt/β-catenin signaling pathway pre-activated have some potential in the treatment of diabetic wounds. In this paper, we review the research status as well as problems in this field.
