[Electric charge of tumor cells of different karyological structure].
The relation was studied between the density of the electrical charge of the surface (DECS) and the karyological structure of the rat ovary tumour (OT) cells. For this purpose the sedimentation rate and electrical mobility of cells from two OT clones were measured. The OT1 and OT2 clones differed in their modal chromosome numbers (44 and 80-90, respectively). An increase in DECS by 4-5% on the average occurs in cells with the chromosome set close to the tetraploid one. The further increase in the chromosome number to the octaploid one does not change DECS. The results obtained show stability of DECS with significant changes in the structure of the OT cells karyotype.
