Abstract:
Objective To investigate the expression of nestin in keloid and hypertrophic scarring.Methods Samples were obtained from patients with normal skin(n=8),flat scars(n=7),keloids(n=8) and hypertrophic scars(n=8),respectively.Immunohistochemistry staining was used to measure the nestin expression in above samples.Nestin positive cells were counted to evaluate the expression levels.Results ①Nestin expression was detected in basal cells,prickle cells,sweat glands,hair follicles,sebaceous glands,and vascular endothelial cells in 8 samples of normal skin,and in fibroblasts in 7 of them.Nestin was also positively expressed in abovementioned cells or skin appendages in samples of flat scars,keloids and hypertrophic scars.②Nestin positive cell counts(epidermic cells,fibroblasts,and vascular endothelial cells) in keloids and hypertrophic scars were significantly higher than those in normal skin and flat scars(P0.05).Conclusions The increased expression of nestin in epidermic cells,fibroblasts,and vascular endothelial cells in keloid and hypertrophic scarring supports a possible role of nestin as fibrosis inducing factors in keloids and hypertrophic scars.
