Abstract

Chemoseparation and immunoseparation techniques have been combined to eliminate malignant clonogenic T lymphoma cells from human bone marrow. Incubation with 5 μ m 2’ -deoxy coformycin and 500 μM deoxyadenosine has eliminated 2 logs of HSB-2 T lymphoma cells from a 20-fold excess of irradiated human bone marrow. Multiple incubations with 3A1 antibody and rabbit complement eliminated approximately 2 logs of HSB-2 cells from similar mixtures. Used in combination, the 2 techniques eliminated up to 4 logs of T lymphoma cells. Incubation of normal human bone marrow under similar conditions failed to affect growth of granulocyte-macrophage colony-forming cell units, burst-form-ing erythroid units, or multipotential erythroid-granulocyte-megakary-ocyte-macrophage colony-forming hematopoietic progenitor cell units.
