Abstract
When a schirrous carcinoma of the human stomach was cultured in diffusion chambers, growth of epithelial and connective-tissue cells was observed. Unlike the original tumor tissue in vitro when the connective-tissue cells did not incorporate thymidine-H3, during growth in diffusion chambers they were labeled. The fraction of cells with labeled nuclei 1 h after injection of thymidine-H3 in the zone of growth averaged 25.1%, much greater than the proportion of labeled cells determined after incubation of the original tumor tissue in vitro (6.6%). Under the conditions of culture, a rapidly proliferating subpopulation of cells with a mitotic cycle 14.8 h in duration was discovered.
