Clones of Friend leukemia cells: differences in karyotypes and responsiveness to inducers of differentiation.
Several clones of Friend leukemia cells have been established which differ in their chromosome composition. These cells also vary with regard to their responsiveness to DMSO, whereas all are responsive to butyric acid. Hence, there appears to be independent assortment of the ability of a cell line to respond to DMSO and to butyric acid, suggesting a different mechanism of action for each agent. Further, individual Friend cells possess the ability to simultaneously contain chloroacetate esterase and heme--two biochemical properties which have previously been believed to be mutually exclusive.
