pubmed:abstractText |
Macrophage precursor cells were cultured from the bone marrow of mice in a liquid culture system in the presence of conditioned medium. To separate their different maturation stages, they were passed through a discontinuous Ficoll density gradient, treated with iron plus magnet or passed through glass bead columns. The different maturation stages have been tested for their function in antibody-dependent cellular cytotoxicity (ADCC) against tumor target cells and in lymphokine-induced macrophage-mediated cytotoxicity. It is shown that the promonocyte, a nonadherent, nonphagocytic precursor cell, is a highly potent cytotoxic effector cell against antibody-coated tumor targets but is totally inactive as an effector cell in lymphokine-induced macrophage-mediated cytotoxicity. In contrast, in the lymphokine-induced macrophage-mediated cytotoxicity the cytotoxic effector cell is a mature macrophage. Thus, ADCC seems to be a function of the macrophage precursor promonocytes, whereas lymphokine-induced cytotoxicity is performed by mature macrophages. The relationship of promonocytes and killer (k) cells in ADCC against tumor targets is discussed.
