title: A non-T, non-B human leukemia cell line (NALM-1): establishment of the cell line and presence of leukemia-associated antigens.
abstract: A permanent hematopoietic cell line, designated NALM-1, was established from the peripheral blood of a patient who was in blastic crisis of Ph1-positive chronic myleocytic leukemia. By means of a panel of specific xenoantisera, the NALM-1 cells were found to express a specific antigen of acute lymphoblastic leukemia and blast leukemia-associated antigen. The cells exhibited no cell-surface receptors for sheep erythrocytes, IgG, or complement; neither cell-surface immunoglobulins nor cytoplasmic immunoglobulin were observed. Furthermore, normal T-cell or B-cell antigens, detectable by the antisera used in this study, were not found in the NALM-1 line.
