Abstract： 目的:观察瘢痕组织与成人正常皮肤中神经丝蛋白(NFP)及其表皮细胞生长因子受体(EGFR)表达变化,阐明神经再支配对增生性瘢痕形成的影响.方法:标本取自烧伤瘢痕愈合后11～26个月来我院进行修复手术的患者,正常对照选自同一患者的供皮区.利用单克隆抗体免疫组织化学染色技术,光镜下观察瘢痕组织及正常皮肤上皮中NFP的表达和EGFR在表皮基底层细胞的标记情况.结果:随着瘢痕的形成,瘢痕组织与正常皮肤上皮中神经纤维的数量表现为早期明显增多,随着瘢痕的成熟,神经纤维的数量逐渐减少.EGFR的表达与NFP的动态变化呈现一致性,瘢痕早期表皮细胞生长因子受体的表达较强,瘢痕后期表达减弱.结论:增生性瘢痕与正常的皮肤中NFP的变化和EGFR活性与创面愈合的结局密切相关.神经调节在瘢痕形成的过程中可能充当了重要的角色.
