To explore the effect of Fas/Apo-1 and Bcl-2 gene expression on mechanism of scar formation.
Immunohistochemical method was applied to defect the expression of Fas and Bcl-2 protein in fibroblasts from 10 cases with normal skin, 10 cases with hypertrophic scar and 10 cases with keloid.
The positive expression rate of Bcl-2 protein in keloid was 83.2%, significantly higher than that in hypertrophic scar (38.6%), (P < 0.01), and the positive expression rate in hypertrophic scar and keloid was higher than that in normal skin (6.78%), (P < 0.01). But the positive expression rate of Fas/Apo-1 protein was 78.4% in normal skin 80.4% in hypertrophic scar, 84.4% in keloid respectively, which showed no significant difference among them (P > 0.05).
Bcl-2 gene but Fas gene may take part in the formation of pathologic scar.
探讨Fas/Apo-1和Bcl-2基因表达在瘢痕形成机制中的作用。
采用免疫组织化学方法检测10例正常皮肤、10例增生性瘢痕及10例瘢痕疙瘩成纤维细胞中Fas和Bcl-2蛋白的表达。
瘢痕疙瘩中Bcl-2蛋白阳性表达率为83.2%,明显高于增生性瘢痕(38.6%),(P<0.01),增生性瘢痕和瘢痕疙瘩中Bcl-2蛋白阳性表达率高于正常皮肤(6.78%),(P<0.01)。但Fas/Apo-1蛋白阳性表达率在正常皮肤为78.4%,增生性瘢痕为80.4%,瘢痕疙瘩为84.4%,三者之间差异无统计学意义(P>0.05)。
Bcl-2基因而非Fas基因可能参与病理性瘢痕的形成。
