title: Acute inflammation effects on in vivo granulopoiesis: comparative studies in healthy and leukaemic mice.
abstract: Mice undergoing an inflammatory reaction, induced by subcutaneous implantation of copper rods, elaborate two kinds of humoral stimulatory factors: the diffusible granulopoietic stimulator (DGS) that enhances diffusion chamber (DC) granulopoiesis, and the serum colony stimulating factor (CSF) that stimulates in vitro granulocyte-monocyte colony growth. We demonstrate here that mice suffering from acute myeloid leukaemia (AML) are unable to augment the production of these humoral stimulatory factors when acute inflammation is induced. Moreover, our results show that increased levels of normal humoral stimulatory factors (DGS and CSF) do not influence the proliferation and/or the differentiation of leukaemic cells implanted in DC.
