Weba hormone secreted by the kidneys that increases the rate of production of red blood cells in response to falling levels of oxygen in the tissues. Effects of EPO. -rapid maturation of comitted marrow cells. -increased circulating reticulocyte count in 1-2 days. -testosterone enhances EPO production, resulting in higher RBC counts in male. Web27 de dez. de 2024 · Hypoxia increases erythropoiesis mediated by hypoxia-inducible transcription factors (HIF), which regulate erythropoietin transcription. Neocytolysis is a physiological mechanism that corrects polycythemia from chronic sustained hypoxemia by transient, preferential destruction of young RBCs after normoxia is restored. i recalled that
