核型: The stemline chromosome number is hypotriploid, with the 2S component occurring at 3.2%. Seventeen to 20 marker chromosomes were common to most S metaphases. Normal X, 13, and 19 chromosomes were absent, and chromosomes 2, 3, 14, 17 and 20 were generally monosomic. The Y chromosome was not detected using QM staining.
