..., with erythropoiesis and hypoxia resulting in downregulation of hepcidin. To date, however, only a few studies have investigated the association between hepcidin levels and these conditions in premature infants who are often exposed to various perinatal factors associated with inflammation and hypoxia [ 11,12...

... Fetal Erythropoiesis? Key Words Angiotensin Angiotensinogen Erythropoiesis Erythropoietin Fetus Abstract Angiotensin affects the growth of many cell types and there have been suggestions that it could influence cells which respond to erythropoietin. During first trimester, human fetal haematopoietic...

... – that is less frequent in this context – in a neonate with methylmalonic aciduria. We used a semisolid erythroid culture system to investigate the effect on in vitro erythropoiesis of organic acids found in excess in this patient: methylmalonic (MMA) and propionic (PA) acids. First, the addition of 10% serum...

...Charles Peters; Michael K. Georgieff; Pedro A. de Alarcon; Robert T. Cook; Leon F. Burmeister; Lance S. Lowe; John A. Widness Erythropoietin, the primary stimulator of erythropoiesis, represents an important potential therapy for the anemia of prematurity. Enhancement of the therapeutic benefit...

...Robert D. Carmichael; Albert S. Gordon; Joseph LoBue Erythropoiesis was stimulated in 2- to 5-day-old neonatal rats suckled by phlebotomized mothers. This was established by increases in: hemoglobin levels, mean corpuscular hemoglobin concentration and percentages of peripheral reticulocytes...

..., of nonpregnant polycythemic mice, and of 12th and 13th day pregnant nonpolycythemic mice. Since polycythemic mice are presumed to have low erythropoietin level, the stimulation of erythropoiesis in the embryonic spleens of polycythemic mothers suggests that fetal erythropoiesis is independent of the maternal one...

... their livers and spleens. These heightened levels of hepatic and splenic erythrogenin most likely form the basis for the ability of the bilaterally nephrectomized neonatal rat to show little impairment in EP production in response to hypoxia.

...M. Djaldetti; J. Ovadia; H. Bessler; P. Fishman; I. Halbrecht The ultrastructural features of the erythropoietic events in 5- to 9-week embryonic livers are described. By the 5th week of gestation, the human embryonic liver becomes an active site of erythropoiesis represented by the formation...

... blood cell transfusion. Although controversial, treatment with recombinant human erythropoietin (EPO) and iron has been recommended to stimulate erythropoiesis; optimal dosing of EPO and iron is still uncertain. Objectives: To assess the validity of a four-quadrant diagnostic plot of iron availability...

... to quantitation of iron delivery to erythrocytes. We first determined normal hematological values for nontreated, dam-suckled Sprague-Dawley rats by measuring markers of erythropoiesis and iron status during the first 12 postnatal days (PND). The experimental group of rats were administered parenteral rhEpo (430...
