This invention provides a method for accelerating the proliferation of human mesenchymal stem cells, which comprises the steps of: transfecting recombinant expression carrier containing EGF to human mesenchymal stem cells, and stimulating with a certain concentration of calcium ions during the transfection process to divide into typical stem cells. Under nude mouse subcutaneous microenvironment induction, the stem cells are further divided into skin tissue stem cells, thus directly taking part in the proliferation of nude mouse hair. This invention can obtain rapidly proliferated human mesenchymal stem cells, thus having a potential application in clinical skin wound treatment.
