Humoral Factors Regulating Erythropoiesis.

Humoral Factors Influencing Erythropoiesis

STRONG EVIDENCE has accumulated to indicate that erythropoiesis in mammals is under the control of a circulating principle, the erythropoiesisstimulating factor ( ESF ) or erythropoietin.1’2 A similar regulatory system may be operative in amphibians and birds.3’4 The ESF appears in large quantities in the plasma of animals subjected to bleeding or low oxygen pressures’ and its production is inh...

Factors Stimulating Erythropoiesis In

By WENDELL F. RossE, THOMAS WALDMANN AND ELEANOR Huu. H YPOXIA AND ANEMIA have been known for many years to stimulate erythropoiesis in mammals, including man.1 In recent years, these stimuli have been shown to have their effect through a humoral factor, erythropoietin.2 J acobson, et al. have suggested that lack of oxygen, relative to the metabolic needs of the animal, is the fundamental stimu...
