However, we did not find major differences in expression levels of MYC, BRD4, HOXB4, and CCND2 mRNA when comparing purified CML cells (KU812, K562) obtained from cultures prepared with or without additional CAL‐72 cells (Figure S11). The gene discussed is CCND2; the disease is chronic myelogenous leukemia, BCR-ABL1 positive.
