Abstract
Single‐laser flow cytometry has been used to study the feasibility of flow karyotyping of human solid tumors. As a model, seven human melanoma cell lines have been used with varying numerical chromosome composition as verified by FCM DNA content measurements and chromosome countings. For all seven cell lines, flow karyotypes that showed a variety of consistent deviations from the normal diploid flow karyotype could be obtained although the resolution of the flow system and varying debris continuum limited the number of resolvable peaks. The predominant changes observed involved the regions normally representing chromosomes 3–8, 9–12, and 13–16. It is concluded that at present the preparation procedure is the main limiting factor for exploring the full potential of flow karyotyping for cytogenetic analysis of solid‐tumor cell lines.Keywords
