HAEMOPOIETIC STEM CELLS IN EXPERIMENTAL HAEMOLYTIC ANAEMIA

Abstract

Phenylhydrazine treatment produced an expansion of spleen CFU (10 x N) and an even greater expansion of spleen ACFU (40 x N). Blood CFU and ACFU levels also increased. While marrow CFU did not change marrow ACFU showed a pronounced drop. The ratio of ACFU/CFU varied between tissues, it was highest in marrow and lowest in peripheral blood. The changes in CFU, ACFU and blood granulocytes are discussed in relation to the radioprotective action of phenylhydrazine pretreatment of mice.
