本文报告甲基膽蒽(Methylcholanthrene)诱发的C3H/ST小鼠脑肿瘤的两种亚细胞成分移植后能够再产生脑肿瘤。前6代在移植后4～7周产生肿瘤,随后的移植在移植后1～3周再产生肿瘤。成分Ⅰ3020xg离心5分钟,重复一遍。所得的为细胞核。成分Ⅱ12100xg离心10分钟。它由不纯一的亚细胞结构组成,主要含有线粒体和粗面内质网。实验结果指出:脑肿瘤可由“祼”核成分或由没有完整核的成分再产生。其潜伏期在传代过程中逐渐缩短。 This report reports that brain tumor can be regenerated after transplantation of two subcellular components of methylcholanthrene-induced C3H / ST mouse brain tumors. The first 6 generations developed tumors 4 to 7 weeks after transplantation, followed by 1 to 3 weeks after transplantation. Ingredients I3020xg centrifuge for 5 minutes, repeat it. The resulting nucleus. Ingredient II 12100xg for 10 minutes. It consists of impure subcellular structures, mainly containing mitochondria and rough endoplasmic reticulum. The experimental results indicate that brain tumors can be regenerated from “祼” nuclear components or from components without intact nuclei. Its incubation period gradually shortened during the passage.
