Regulatory Action of Charred Gossamer Urocteae on the Functions of Mouse Oral Fibroblasts
چکیده انگلیسی

ObjectiveTo explore the influence of charred Gossamer urocteae (CGU) on the functions of primary cultured mouse oral fibroblasts and reveal its mechanism in wound healing.MethodsCGU was extracted with different solvents and ethanol extract (EE), ethyl acetate fraction (EF), n-butanol fraction (BF) and aqueous fraction (AF) were obtained. The effects of different fractions on the proliferation, matrix metalloproteinase-2,9 (MMP-2,9) activities, synthesis of collagen and tissue inhibitor of metalloproteinase 1 (TIMP-1) in the mouse oral fibroblasts were determined by MTT, gelatin zymography, chloramine-T method, and enzyme-linked immunosorbent assay (ELISA) respectively.ResultsEE, EF and BF at high concentrations could significantly inhibit proliferation of fibroblasts (P<0.05 or P<0.01), and at low concentrations EF and BF could promote proliferation of fibroblasts, and BF and AF could significantly inhibit collagen synthesis (P<0.05 or P<0.01). EE, EF and AF at high concentrations could significantly increase the MMP-9 activity, and BF and AF could significantly inhibit synthesis of TIMP-1.ConclusionCGU at high concentrations can inhibit the proliferations of fibroblasts and synthesis of collagen, and in healing of wound, CGU at high concentrations possibly has the functions of anti-fibrosis and anti-scar, and the mechanism to promote degradation of collagen is possibly related to the increase in MMP-9 activity and the inhibition of TIMP-1 synthesis.
