Karyotype array of the cervical carcinoma HT-3. The HT-3 array with the attached table shows that the total chromosome number is quasi-clonal at 68±3. The copy numbers of 60-85% of the chromosomes were 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 14 out of 20 cells. Comparison of the karyotype array of HT-3 with those of the three carcinomas shown above in Figures 6, 7 and 8 reveals at a glance that all four carcinomas have distinct individual karyotypes.
