Objective:
To explore the method of constructing tissue-engineered skin using melanocytes and bone marrow mesenchymal stem cells (BMSCs) in vivo.
Methods:
Melanocytes were isolated from human foreskin. BMSCs were isolated from human bone marrow. Both of them were co-cultured at a ratio of 1:10, and then were implanted into the collagen membrane to construct the tissue-engineered skin, which was applied for wound repair in nude mice. The effectiveness of wound repair and the distribution of melanocytes were evaluated by morphological observation, in vivo 4,6-diamidino-2-phenylindole, dihydrochloride (DAPI) fluorescent staining tracing, HE staining, S-100 immunohistochemistry, and transmission electron microscopy.
Results:
The wounds were satisfactorily repaired among the nude mice. The melanocytes were distributed in the skin with normal structure, as confirmed by DAPI fluorescent staining tracing, HE staining, S-100 immunohistochemistry, and transmission electron microscopy.
Conclusion:
Melanocytes and BMSCs, after proper in vitro culture at an appropriate ratio, can construct the tissue-engineered skin with I type collagen membrane.
