摘要
背景:有研究表明细胞因子抑制剂吡非尼酮通过调控多种细胞因子,抑制成纤维细胞的生物学活性,其在内脏器官的抗纤维化作用的研究和应用取得了良好的进展,但对于皮肤增生性瘢痕及成纤维细胞是否有影响及其机制尚不清楚。目的:观察细胞因子抑制剂吡非尼酮对人增生性瘢痕成纤维细胞增殖的影响。方法:采用组织块法培养人增生性瘢痕成纤维细胞,实验取第3-6代生长状态良好的对数生长期细胞。根据吡非尼酮不同质量浓度分为对照组(吡非尼酮0 g/L),吡非尼酮0.15,0.3,1 g/L组,共干预12,36,48 h。结果与结论:MTT,反转录-聚合酶链式反应和酶链免疫吸附实验结果显示,与对照组相比,吡非尼酮0.15,0.3,1 g/L组细胞增殖情况、转化生长因子β1 mR NA的表达、Ⅰ、Ⅲ型胶原蛋白的分泌量均降低(P<0.05),其中吡非尼酮1 g/L组降低最明显(P<0.05)。干预24,48,72 h后,吡非尼酮0.15,0.3,1 g/L组间细胞增殖抑制率、Ⅰ、Ⅲ型胶原蛋白的分泌量均差异有显著性意义(P<0.05)。结果证实,细胞因子抑制剂吡非尼酮对体外培养的人增生性瘢痕成纤维细胞胶原蛋白的分泌、转化生长因子β1的表达及细胞增殖活性有明显的抑制作用。
BACKGROUND:Studies have shown that cytokine inhibitor pirfenidone can inhibit biological activity of fibroblasts by regulating a variety of cytokines. It has made good progress in the research and application of anti-fibrosis of internal organs, but the effect and mechanism for hypertrophic scars and skin fibroblasts are unclear. OBJECTIVE:To investigate the effect of pirfenidone on human hypertrophic scar fibroblasts. METHODS:Human hypertrophic scar fibroblasts were cultured using tissue culture method. Passages 3-6 cel s grew wel in the logarithmic growth phase were col ected. Cel s were divided into the control group (0 g/L pirfenidone), 0.15, 0.3 and 1 g/L pirfenidone groups according to different mass concentrations. Cel s were intervened for 12, 36 and 48 hours. RESULTS AND CONCLUSION:MTT, reverse transcription-polymerase chain reaction and enzyme-linked immunosorbent assay results demonstrated that compared with the control group, cel proliferation, transforming growth factorβ1 mRNA expression, types I and III col agen secretion were decreased in the 0.15, 0.3 and 1 g/L pirfenidone groups (P〈0.05), and the decrease was most significant in the 1 g/L pirfenidone group (P〈0.05). At 24, 48 and 72 hours after intervention, significant differences in inhibitory rate of cel proliferation and the secretion of types I and III col agen were detected among 0.15, 0.3 and 1 g/L pirfenidone groups (P〈0.05).&amp;nbsp;Results confirmed that pirfenidone apparently inhibited the secretion of col agen of hypertrophic scar fibroblasts cultured in vitro, transforming growth factorβ1 expression and cel proliferation and viability.
