[Morphological characteristics of colonic cancer in organ cultures].

Three types of human colonic carcinoma were studied in organ cultures. Apart from the formation of glandular structures and processes not structurally differing from those in human bodies, there occurred complexes of cancer cells spreading beyond the boundaries of the explant and forming no structures at all. It was shown that in organ cultures, cancer cells retained their capacity to synthesize carcinoembryonic antigen.
