- Abstract
In the 15-days pig embryo EI with the central macrophage is not available. Initially the morphologically similar formations (without a phagocytated nucleus) are coming apparent just in the 25- days pig embryo and the full-fledged hepatic EI formation with the central macrophage and the phagocytated nuclei of erythroblasts refers approximately to the 55th day of the pig embryonal development. An extrusion of the erythroblast's nucleus with its following phagocytosis by the central macrophage of island, what is highly typical for erythroblastic islands, was also shown. Thus, two types of erythropoiesis - the primitive and definitive ones are gradually interchanged in the liver during the coming to being process of the pig embryo's hemopoiesis.
