摘要 目的:分析正常皮肤、增生性瘢痕和瘢痕疙瘩成纤维细胞在形态学、生长动力学及生物学的特性。方法:采用组织块培养法培养细胞;MTT法检测细胞在血清饥饿状态下的活性;免疫组织化学法检测3种成纤维细胞中结缔组织生长因子(CTGF)和胸苷磷酸化酶(TP)的表达。结果: 正常皮肤、增生性瘢痕和瘢痕疙瘩成纤维细胞在形态与生长动力学上基本相似,血清饥饿对不同来源的成纤维细胞生长的影响并没有显著的差别。CTGF、TP在增生性瘢痕和瘢痕疙瘩成纤维细胞中均呈强阳性表达,而在正常皮肤成纤维细胞中的表达却很微弱,且有显著差别。结论: 正常皮肤、增生性瘢痕与瘢痕疙瘩3类成纤维细胞在体外培养状态下,其形态、生长特性以及对血清饥饿的影响无显著差异。3类成纤维细胞对细胞因子具有不同的反应特性。
