摘要 通过组织块法分离并原代培养人肛瘘管壁组织,用胰蛋白酶和乙二胺四乙酸(EDTA)消化成纤维细胞、上皮细胞,获得更加纯化的成纤维细胞;以DMEM培养液为基础培养蒸,添加胎牛血清(体积分数10%)、青霉素(100U/L)和硫酸链霉素(100U/L),置37℃、5%CO2培养箱中培养。倒置相差显微镜和细胞爬片HE染色。观察成纤维细胞形态结构,并对培养成纤维细胞行角蛋白、波形蛋白免疫细胞化学鉴定.结果分离后的成纤维细胞在第4~12h于体外快速贴壁,第2~4天进入对数期生长、增殖期。细胞起源鉴定波形蛋白免疫细胞化学染色为阳性,角蛋白免疫细胞化学染色为阴性。提示该方法所获得的肛瘘管壁成纤维细胞可在体外稳定培养,不含有杂质细胞。可为在细胞分子水平上研究肛瘘瘘管愈合的机制提供可靠的细胞模型。
