[Anti-leukemia resistance and growth-regulating molecules in hematopoietic tissue].

The analyzed data from literature suggest that the growth-regulating molecules of the hematopoietic tissue are a part of the antileukemic defence system of the body. This component of the antitumour resistance is the first one formed during the multicellular organism evolution. It is of special significance in the tissue stimulated to proliferation in which the number of antiblastic defence cell effectors diminishes in the regenerating tissue while the number of progenitor cells having the oncogenic potential increases.
