Intraperitoneal inoculation of neonate Sprague Dawley rats with cell-free extracts containing retrovirus-like particles from DMBA-induced rat mammary tumors resulted in a fivefold increase of benign mammary neoplasias in the survivor animals, in comparison to the spontaneous tumor incidence rate. In addition, four animals developed metastasizing abdominal adenocarcinomas. The ascitic cells of one of the abdominal tumors were established as a permanent tissue culture line (HH-1). After subsequent animal passage, cells of the permanent line HH-9 clone 14 showed increased malignancy manifested by the number of takes per animals injected, and by the number of remote metastases observed.
用含有来自二甲基苯并蒽(DMBA)诱导的大鼠乳腺肿瘤的逆转录病毒样颗粒的无细胞提取物对新生斯普拉格-道利大鼠进行腹腔接种,与自发肿瘤发生率相比,存活动物的良性乳腺肿瘤增加了五倍。此外,四只动物发生了转移性腹部腺癌。其中一个腹部肿瘤的腹水细胞被建立为永久性组织培养系(HH-1)。在随后的动物传代后,永久性系HH-9克隆14的细胞显示出恶性程度增加,表现为每只注射动物的接种成功率以及观察到的远处转移数量。
