Karyotype
This is probably a pseudotriploid human cell line with the modal chromosome number of 68, occurring in 24% of cells, but cells with both 69 (22%) and 70 (18%) chromosome counts also occurred frequently. Cells with higher ploidies occurred at 7.0%.
Karyotypes were extremely complex. Consistently there were 20 to 25 marker chromosomes (>30% of total chromosome content) per cell. Most marker chromosomes had complex structural rearrangements, and the origin of chromosome segments of these markers often defied identification. Among the frequently found markers were 8p+, 11p, a large metacentric [?t(3qter--3q12::?--C--?::3q12--3qter)] der(?13)T(1;?13) (p13;?q14), and many others. There was only one normal X chromosome. Normal N3 and N13 were not found.
