Cytogenic data:

modal number = 78; range = 73 to 80. The cell line is aneuploid human female, with chromosome counts in the hypertriploid range. The X chromosomes are all abnormal. Normal chromosomes N10 and N13 are clearly under-represented, with chromosomes N2, N12, and N17 also tending to be. Chromosome N8 is over-represented with respect to the copy number of other normal chromosomes, and chromosomes N5 and N18 also usually have more copies than most chromosomes. Four marker chromosomes are found: iso(13q), 10q+, del(X)(q22:), del(11)(p11:).
