| 摘 要： | 目的探讨血小板源生长因子 (PDGF)及其受体在瘢痕增生过程中的作用。方法采用多克隆抗体并以免疫组织化学方法检测 9例正常真皮、7例肉芽组织及 34例增生性瘢痕标本中的PDGF及其受体和Ⅰ型胶原的表达情况。结果PDGF及其受体在肉芽组织和增生性瘢痕中的表达明显增强 ,在 6个月以内的增生性瘢痕中达到高峰 ,此后逐渐减弱 ;而正常真皮组织中仅少数标本呈微弱表达 (P <0 .0 5 )。结论PDGF及其受体表达的增强可能与瘢痕的增生密切相关

| Abstract: | ObjectiveTo investigate the role of platelet-derived growth factor(PDGF) and its receptor in the development of hypertrophic scar. MethodsThe expression of PDGF and its receptor were detected in biopsy specimens of 9 pieces of normal skin, 7 pieces of granulation tissue of burn wound and 34 pieces of hypertrophic scar by immunohistochemical staining using specific polyclonal antibodies.ResultsPDGF and its receptor markedly increased in granulation tissue and hypertrophic scars, reaching the peak in the hypertrophic scars within 6 months and then decreased after the peak, whereas PDGF and its receptor expressed weakly in only a few normal skin specimens, and the differences were significant( P<0.05).ConclusionsThe increasing expression of PDGF and its receptor may be related to the development of hypertrophic scar. |
