摘要 目的:研究人腹膜间皮细胞(HPMC)中尿素转运蛋白(UTB)的表达。方法:收集患者腹膜透析液,采用细胞悬液分离HPMC,并进行HPMC原代及传代培养;免疫组化法鉴定体外培养细胞;抽提HPMCRNA,RT-PCR法扩增基因片段,以人肾髓质为对照,对扩增产物进行测序分析。结果:HE染色及免疫组化鉴定细胞角蛋白和波形蛋白染色均为阳性,细胞第Ⅷ因子相关抗原及白细胞CD45抗原染色均呈阴性,证实培养细胞为HPMC,纯度可达96%以上,RT-PCR扩增产物经电泳检测与预期结果相符243bp,扩增产物测序结果与UTB序列比较结果一致。结论:HPMC中存在UTB表达,本研究有助于进一步了解腹膜透析超滤不充分的机制,为其临床防治提供依据。
