Abstract
Liver epithelial cells from a young rat were cultured and passaged for a long period until they showed a malignant transformation (tumorigenicity in athymic mice), to know when an autocrine growth factor is produced in the course of a spontaneous malignant transformation of normal cells in vitro. The cells initially showed a cellular transformation and an increased growth rate, then produced an autocrine growth factor after Passage 55, and finally the cells after Passage 105 showed a malignant transformation (tumorigenicity in vivo). It is suggested that in addition to an autocrine growth factor, some other factors might be related to a malignant transformation (tumorigenicity in vivo).Entities:
