title: Drug sensitivity studies on clonal cell lines isolated from heteroploid tumor cell population. II. Sensitivity of clones growing in suspension cultures.
abstract: NK/S cell line and its clonal lines 6 and 10 were established in culture from NK/Ly mouse lymphoma. The clones differed from each other and from the parent line in chromosome pattern and growth rate. Clone 6 cells were polyploid and more sensitive to dianhydrogalactitol than the diploid clone 10 cells. However, clone 10 cells were more sensitive to adriamycin. A very small difference in sensitivity was found with vincristine. It was concluded that sensitivity of clones originating from the same parent population is drug-related.
