Abstract excerpt
We have developed a murine mammary tumor cell line, MC4-L4, and after 15 passages, a spindle-shaped population became evident. The cuboidal cells, MC4-L4E, cloned by limit dilution, proved to be epithelial tumor cells. When inoculated in syngeneic mice, they gave rise to invasive metastatic carcinomas expressing estrogen and progesterone receptors. These tumors regressed after anti-progestin treatment and stopped...
