based on these observations and recent observations by other groups on the hematopoietic effects of other monokines including tumor necrosis factor alpha , we argue that mononuclear phagocytes serve as important regulators of hematopoiesis by producing monokines that , in turn , induce the expression of multiple hematopoietic growth factor genes in stromal cells of the hematopoietic microenvironment .
