title: Flow cytofluorometric analysis of a human aneuploid cell line growing in vitro and in intraperitoneal diffusion-chambers.
abstract: An aneuploid established cell line originating from human skin (NCTC 3075) was cultivated in vitro culture and in intraperitoneal diffusion chambers in hamsters. In in vitro cell culture a near tetraploid cell line dominated. Shortly after implantation into the diffusion chambers in the peritoneal cavity of hamsters a selective lysis of cells with near tetraploid DNA content occurred, with a relative increase of a diploid subline. After 5 days in the hamster a tetraploid cell line again dominated as in in vitro culture. The use of flow cytofluorometry for ploidy analysis and changes in cell cycle traverse is demonstrated. The possible use of this model system in studies of response to therapy is discussed.
