Therefore, it is extremely accelerate the construction of the dermis in skin tissue engineering. OBJECTIVE: To investigate the effects of bone marrow mesenchymal stem cells/calcium alginate gel, basic Wang Nan, Dalian Medical University, Dalian , Liaoning Province, China Corresponding author: Li Na-ran, Senior experimentalist, Morphology Center, Shenyang Medical College, Shenyang , Liaoning Province, China Corresponding author: Yang Xiao-xia, Master, Professor, School of Medical Application Technology, Shenyang Medical College, Shenyang , Liaoning Province, China Accepted: P.O.

2 . fibroblast growth factor and degradation membrane on the repair of full-thickness skin defects. METHODS: Bone marrow mesenchymal stem cells were isolated from 15 New Zealand rabbits, and then cultured, amplified, subcultured and purified. Three full-thickness skin defects were made on the back of every rabbit, and randomly treated with bone marrow mesenchymal stem cells/calcium alginate gel, basic fibroblast growth factor and degradation membrane as experimental group, bone marrow mesenchymal stem cells/calcium alginate gel as control 1 group, and calcium alginate gel as control 2 group. The wounds were all covered with amniotic membrane. After 7, 14, 21 days, new wound tissues were taken for hematoxylin-eosin staining, immunohistochemistry staining and image analysis. RESULTS AND CONCLUSION: Dermis tissues in the experimental group were obviously thicker than those in control 1 and control 2 groups; there were more fibroblasts, vessels and collagen fibers in the experimental group. Especially at 14 and 21 days after operation, epidermal hyperplasia was faster with a larger coverage area in the experimental group, and at 21 days, the new epidermal tissues mainly exhibited multi-layered structure, which was superior to the control 1 and 2 groups. It follows that the combination of bone marrow mesenchymal stem cells/calcium alginate gel, basic fibroblast growth factor and degradation membrane for skin defects can accelerate the repair and regeneration of the dermis, and thus promote the epidermis regeneration and reconstruction.
