将人类鼻咽癌细胞株与小鼠心脏的器官块在生物膜(肾包膜)包裹下进行器官培养,在7、3、5天的不同培养时期取出标本进行扫描电镜观察,证实了瘤细胞向器官靠拢、紧贴,伸出伪足和向器官内浸润的微细表面特征。瘤细胞在靠拢器官细胞后,首先伸出比正常数多而长的微绒毛和丝状伪足,以其末梢分枝的微小器官像鹰爪般的抓住器官细胞的突起部份,使两者 The human nasopharyngeal carcinoma cell line and the organ fragment of the mouse heart were organ cultured under the wrapping of the biofilm (renal capsule), and the specimens were taken out at different culture periods of 7, 3 and 5 days for scanning electron microscopy to confirm that the tumor cells Close to the organ, close to, extending the pseudo-foot and the infiltration of organs within the fine surface features. Tumor cells close to the organ cells, the first than the normal number of long and more than the protruding microvilli and filopodia, with its peripheral branches of tiny organs like the eagle-like grasp of the protruding part of the organ cells, so that the two By
