Figure 7.

Karyotype array of the near-diploid cervical carcinoma C-33A. The C-33A array with the attached table, prepared as described in Figure 6, shows that the total chromosome number of C-33A is 46±1 and is thus quasi-clonal. The copy numbers of C-33A chromosomes were 70-90% clonal, forming parallel lines in the array. The non-clonal chromosomes included intact chromosomes with near-clonal copy numbers and new non-clonal marker chromosomes, which were found in four of 20 cells. A comparison of the arrays of C-33A and of C-4II shows at a glance that each carcinoma had an individual clonal karyotype.
