人脑胶质瘤细胞原代培养实验模型的构建

目的:探索人脑胶质瘤细胞原代培养的方法,提高原代培养的成功率,快速构建人脑胶质瘤细胞体外试验模型。方法:分别采用组织块培养法和酶消化法对12例人脑胶质瘤细胞进行原代培养,比较两种方法的培养效果;通过倒置相差显微镜和激光共聚焦显微镜观察细胞的形态学特点;通过生长曲线的测定研究体外培养细胞的生长特性。结果:原代人脑胶质瘤细胞短期培养成功,并可传代。经组织块培养法成功率较低为33.3%;经酶消化法短期培养成功率为83.3%,明显高于组织块培养法。培养成功的细胞状态稳定,增殖活跃,有明显的对数生长期。结论:用酶消化法可进行人脑胶质瘤短期体外培养,且成功率较高,适宜建立体外细胞培养模型。

Clinicopathological Analysis of a Primary and Solitary Brain Plasmacytoma: Case Report with an Encepha-locoele

A primary and solitary plasmacytoma with an encephalocoele is an extremely rare tumortx. The origin of plasmacytoma cells has not been clarified, but a number of studies have suggested the possibility that it originates from the meninges and reticular cells of the Virchow-Robin space. Other studies have suggested that plasmacytoma cells may possibly arise from original reticular and stem cells.
