This study was set to explore a new strategy for repairing skin wounds, co-transplantation of mesenchymal stem cells from Wharton’s Jelly of the human umbilical cord (hUC-Wharton’s jelly-MSCs) and microparticles. A mixture of hUC-Wharton’s jelly-MSCs and microparticles was co-transplanted to 10-mm diameter, full-thickness, mid-dorsal, excisional skin wounds of mice. After 7, 14, and 21?days, the tissue sections were sampled for reconstruction analysis and histological examination. Our results showed that hUC-Wharton’s jelly-MSCs possess the potentials for multi-directional differentiation. After co-transplantation, there was remarkable development of newborn skin and its appendages. Newly generated layers of epidermis, sebaceous glands, hair follicle, and sweat glands were observed. This promising innovative strategy could significantly increase the quality of repair and regeneration of skin after injuries.
