Glucocorticoids Induce the Maintenance and Expansion of an Immature CFU-E Erythroid Progenitor Population in Humans

Glucocorticoids are widely used to increase red cell production in a number of hematological disorders including Diamond Blackfan anemia (DBA). Despite their clinical effectiveness we do not fully understand the mechanistic basis for the regulation of human erythropoiesis by glucocorticoids. To improve the clinical management of these patients, we studied the mechanisms of dexamethasone (Dex) on human erythroid progenitors. We employed an...
