[Characteristics of hematopoiesis in athymic nude mice].

The bone marrow, peripheral blood and spleen state was studied from the age aspect in Nude mice characterized by recessive nu mutation. A number of blood system peculiarities were revealed in homozygotic (nu/nu) mice by which they differed from the heterozygotic (nu/+) animals: low peripheral blood, bone marrow and spleen lymphocyte count, erythropoiesis depression in the bone marrow and erythroid element hyperplasia in the spleen.
