Abstract:

BACKGROUND: Umbilical cord mesenchymal stem cells possess multipotent differentiation and self-replication abilities, and can differentiate into osteoblasts, chondrocytes, smooth muscle cells and vascular endothelial cells, which contribute to reepithelialization and angiogenesis.
OBJECTIVE: To compare effects of umbilical cord mesenchymal stem cells and chitosan-gelatin sponge in skin wound healing.
METHODS: Thirty male Sprague-Dawley rats were equivalently randomized into model, chitosan-gelatin sponge and stem cell groups. 3×3 cm full-thickness skin defects were created on the rat dorsal area in each group, and 1 day later, model rats in each group were given intradermal injection of PBS, chitosan gel or umbilical cord mesenchymal stem cells, respectively, for successive 15 days.
RESULTS AND CONCLUSION: Compared with the model group, the wound healing rate was higher, the epidermal thickness was decreased, and the collagen fiber area was larger in the chitosan-gelatin sponge and stem cell groups. Furthermore, the healing effect in the chitosan-gelatin sponge group was superior to that in the stem cell group. To conclude, both chitosan-gelatin sponge and umbilical cord mesenchymal stem cells, especially umbilical cord mesenchymal stem cells, can effectively repair skin defects.
