摘要: 目的 了解内皮素-1和碱性成纤维细胞生长因子(bFGF)在瘢痕疙瘩组织的表达情况。方法 组织活检标本分为3组,瘢痕疙瘩、萎缩性瘢痕和正常皮肤。用地高辛标记的cDNA探针,采取冰冻切片原位杂交的方法检测内皮素-1和bFGF mRNA的表达。结果 瘢痕疙瘩真皮组织内内皮素-1 mRNA的表达明显强于萎缩性瘢痕和对照组。阳性染色主要位于真皮浅层血管和部分真皮成纤维细胞。瘢痕疙瘩组6/8例真皮成纤维细胞内皮素-1 mRNA阳性,且呈弥漫性分布;萎缩性瘢痕和正常皮肤真皮成纤维细胞内皮素-1mRNA无阳性着色。结论 内皮素-1和bFGFmRNA在瘢痕疙瘩组织中的过度表达提示内皮素-1和bFGF可能在瘢痕疙瘩的形成中起一定作用。

Abstract: Objective To determine the expression of endothelin-1(ET-1) and basic fibroblast growth factor(bFGF) mRNA in keloid lesion. Methods Skin biopsies were obtained from patients with keloid, normal scar and healthy controls. The expression of ET-1 and bFGF mRNA was evaluated by in situ hybridization with Dig labelled cDNA probe. Results Dermal ET-1 and bFGF mRNA staining was more intensive in keloid lesion than that in scar and control tissue. Increased ET-1 staining was mainly observed in the superficial dermal vessels and dermal fibroblasts. ET-1 positive fibroblasts were found in 6 of 8 patients with keloid and diffusely distributed. Conclusion The overexpression of ET-1 and bFGF in keloid indicates that ET-1 and bFGF may play a role in the formation of keloid.
