人成纤维细胞的原代培养及鉴定

目的建立不同组织来源成纤维细胞的培养方法并比较其培养差异。方法用消化法和贴壁法分离人胚胸主动脉成纤维细胞与人胚肺成纤维细胞,利用差速培养法纯化成纤维细胞,并对所培养的细胞进行倒置显微镜观察和苏木素-伊红染色,观察成纤维细胞形态,并对培养的细胞行波形蛋白免疫染色鉴定。结果接种24 h后人胚胸主动脉成纤维细胞全部贴壁,48 h后细胞体积增大并伸出伪足,形状以梭形或不规则形为主;而消化的人胚肺组织中细胞形态不一,经继续培养4～5代后,培养物完全由成纤维细胞构成。结论用胶原酶Ⅰ消化人胚胸主动脉成纤维细胞效果好,而用胰蛋白酶液消化人胚肺成纤维细胞效果较好,用差速生长纯化的成纤维细胞可用于实验研究。

Primary culture and identification of human fibroblasts

Objective To set up the method of the culture of human fibroblasts from different sources and compare their discrepancy. Methods Human embryonic thoracic aortic fibroblasts and embryonic lung fibroblasts were isolated by enzyme digestion and adherence,and purified by means of differential attachment technique.The morphology and phenotype characterization of cultured fibroblasts was inspected by inverted microscope after hematoxylin-eosin staining and the cells were identified by immunocytochemical staining ...
