Abstract Two new cell lines, EM-2 and EM-3, were established from a patient who relapsed with chronic myelogenous leukemia (CML) after marrow transplantation. Both lines have been in continuous culture for one year, are heteroploid with multiple copies of the Ph1 chromosome, and are of host origin. Both lines expressed an increased frequency of NBT dye- reducing cells after incubation with retinoic acid (RA). The lines were also examined for the expression of myeloid determinants recognized by a panel of monoclonal antibodies before and after incubation with RA or phorbol-ester (TPA). Similar studies were conducted with BB-2 monoclonal antibody recognizing a B cell blast associated antigen. We found that EM-2 and EM-3 have myeloid features and that both lines could be induced to undergo further myeloid differentiation with TPA and/or RA. Incubation of both lines with TPA increased the expression of the B cell blast associated antigen.
