Abstract
The influence of tetra phorbol diesther (TPA) on primary blast cells of patients with acute leukemia and blastic crises of chronic myelogenous leukemia and the influence of the condition medium (CM) of the primary and TPA-treated blast cells on the proliferation of HL-60 cell line has been studied. The level of interferon-alpha (IFN-alpha) in CM was tested. TPA inhibited proliferation and induced macrophage-like differentiation of primary AML blast cells and these changes were accompanied by modulation of IFN-alpha expression in CM. The effect of blast CM on proliferation of HL-60 was both inhibitory and stimulating and depended on the time of treatment and individual characteristics of patients. It has been shown that the level of IFN-alpha in CM was not correlated with antiproliferative effect of CM. The role of individual differences in capability of primary blast cells to be induced by differentiated agents and the nature of these differences are discussed.
期刊介绍：
The journal publishes original theoretical and clinical studies, lectures, reviews, and practical notes concerning various problems of hematology and clinical and industrial transfusion. The journal provides information on the etiology, pathogenesis, diagnosis and treatment of blood disorders as well as on related non-hematological conditions (internal diseases, poisoning, exposure to ionizing radiation etc.).
