Abstract:
:Exogenous growth factors could accelerate the process of wound healing. However, the underlying mechanisms have not been clearly clarified. The aim of the present study was to investigate the effect of epidermal growth factor (EGF) and basic fibroblast growth factor (bFGF) on the expression of type I collagen (cola1), type III collagen (cola3), and Elastin in fibroblasts, which are widely expressed in fibroblasts and promote the function of fibroblasts. We measured the levels of cola1 and cola3 in human fibroblast cells cultured in medium containing EGF or bFGF at concentrations ranging from 0.1 to 1000 μg/L by Western blotting and RT-PCR assays, and found that EGF or bFGF enhanced the expression of cola1 and cola3 in a concentration-dependent manner. We further discovered that after stimulation with EGF or bFGF in human fibroblast cells, mitogen-activated protein kinases (MAPK) family members were generally activated, whose expression trend was consistent with that of cola1, cola3, and Elastin. In summary, in this study, we uncovered that exogenous growth factors enhance the expression of cola1, cola3, and Elastin, which is probably regulated via activating MAPK signaling pathway.
