    Keratin 19 stem cells are primary skin stem cells. It is usually considered that the positive expression of K-19 can only be detected in the skin tissue during the period of embryonic development. However, our study has found that the expression of K-19 skin stem cells can be found in the wound of patients in the process of skin regenerative therapy. After the deep burns wound was treated with MEBT/MEBO for 24h, 4d, 7d, 14d, 21d and 28 d respectively, incision biopsy in the wound for ultra-low- temperature fixation and immunofluorescence treatment, and K-19 positive cells were identified with high multiple electronmicroscope. This type of cells appeared in 24th hour, reached its peak in 14th day after MEBT/MEBO treatment, and then disappeared gradually with the wound recuperation after 21-28 days. The positive expression of K-19 cells is the mark of the embryonic physiological healing of all layers of the skin, and reveals the main mechanism of skin tissue organ regeneration technique.
