Abstract

The initiation of a cultured human colon carcinoma line on a feeder layer of confluent fibroblasts is described. Attempts to initiate cultures without fibroblast feeder layers were not successful. Two sub-lines (designated HCT C and HCT C Col) were isolated and weaned from cells growing on the surface of the feeder layer. The sub-lines had different morphologies, secreted different levels of carcinoembryonic antigen (CEA) into the medium of confluent cultures and had slightly different karyotypes. Both sub-lines grew in semi-solid medium and formed xenografts when injected s.c. into athymic nude mice. Analysis of radioiodinated cell membrane components indicated small, but significant differences between the sub-lines.
