Abstract: The human amniotic membrane, type Ⅰ collagen were used as the scaffold, and the hair follicle stem cells and dermal cells from goat were used as the seed cells to construct the tissue engineered skin which would be have skin appendages such as hair follicles and sweat glands. Tissue engineered skin was constructed in vitro, and then was transplanted into goats to observe and test its repairing effect on damaged skin(as experimental group,and the transplantation of amniotic membrane instead of the tissue engineered skin was set as control). The results showed that hair follicle was formed when the tissue engineered skin was cultured for 25 days in vitro and the epidermal cells were keratinized by the scanning electron microscopy. The scar area was measured at 30, 60, and 90 days after transplantation. Results showed that the scar area in the experimental group was significantly lower than the control (P<0.01). When transplanted for 270 days, histological section of the transplanted skin showed that the dermal, epidermal and the hair follicles formed in the experiment group, and the control group were just connective tissues. In conclusion, the tissue engineering skin with hair follicles was successfully constructed using goat hair follicle stem cells and dermal cells as seed cells.
