Abstract:
Objective To investigate the effect of bFGF and MSCs autografting on expression of PCNA and Ⅷ-R Ag of porcine skin defect wound. Methods Six male minipigs were used to produce 48 full-thickness skin wounds, each wound area about 2.54 cm~ 2 on both sides of the back (8 wounds per pig). These 48 wounds were randomly treated with bFGF, MSCs, bFGF+MSCs, and normal saline (12 wounds for each treatment). The tissue from the wounds was harvested on day 3, 7, 14 after surgery, then used for HE staining and immunohistochemical staining for proliferating cell nuclear antigen (PCNA) and factor Ⅷ related antigen (Ⅷ-R Ag). Results Granulation tissue was presented in all groups on day 3 and 7 after wound, most abundant in the wounds treated with bFGF+MSCs, as well as blood capillary formation. PCNA expression increased after skin injury, reached the peak on day 7, most in the granulation tissue, and lasted to day 14, then began to decrease. On day 3, 7, 14 after skin injury, PCNA expression was the most highest in the wounds treated with bFGF+MSCs. Ⅷ-R Ag-positive cells in the wounds treated with bFGF+MSCs were significantly more than that of the other three treatments (P
