Circulating primitive erythroblasts establish a functional, protein 4.1R-dependent cytoskeletal network prior to enucleating

Scientific Reports, 2017
Hematopoietic ontogeny is characterized by distinct primitive and definitive erythroid lineages. Definitive erythroblasts mature and enucleate extravascularly and form a unique membrane skeleton, composed of spectrin, 4.1R-complex, and ankyrinR-complex ...

Krüppel-Like Transcription Factor KLF1 Is Required for Optimal γ- and β-Globin Expression in Human Fetal Erythroblasts. [PDF]

PLoS ONE, 2016
In human adult erythroid cells, lower than normal levels of Krüppel-like transcription factor 1 (KLF1) are generally associated with decreased adult β- and increased fetal γ-globin gene expression. KLF1 also regulates BCL11A, a known repressor of adult γ-

A mechanism of ineffective erythropoiesis in β-thalassemia/Hb E disease

Haematologica, 2010
Background Cells respond to stress stimuli through a number of response pathways, of which one of the most important and well characterized is the unfolded protein response.

Generation of transgene-free human induced pluripotent stem cells from erythroblasts in feeder-free conditions

STAR Protocols, 2022
Summary: This protocol describes the generation and characterization of human induced pluripotent stem cells (hiPSCs) from erythroblasts. A key difference with classical protocols is the reprogramming of erythroblasts from a simple blood draw as opposed ...

Cytological evaluation of the influence of high and low doses of bisphenol A on an erythroblastic cell line of porcine bone marrow

Journal of Veterinary Research, 2018
Introduction: Bisphenol A (BPA) is a substance widely used in industry for the production of polycarbonates and epoxy resins used in packaging and containers for beverages, contact lenses, compact discs (CDs), window panes, and many other elements.

The majority of the in vitro erythroid expansion potential resides in CD34− cells, outweighing the contribution of CD34+ cells and significantly increasing the erythroblast yield from peripheral blood samples

Haematologica, 2010
The study of human erythropoiesis in health and disease requires a robust culture system that consistently and reliably generates large numbers of immature erythroblasts that can be induced to differentiate synchronously.

No Mitoses in Basophilic Erythroblasts

Experimental Biology and Medicine, 1974
SummaryIn the rabbit, under conditions in which mitoses accumulated in the acidophilic erythroblasts, none were observed in the basophilic erythroblasts. On the basis of certain assumptions, the basophilic erythroblasts were divided into two size classes: of average long diameters (as measured here) 10.3 and 8.4 nm.

THE METABOLISM OF HUMAN ERYTHROBLASTS [PDF]

Journal of Clinical Investigation, 1936
The metabolism of human nucleated red blood cells has not previously been determined because of difficulties in procuring material. In most anemias the number of nucleated erythrocytes in the blood is so small in relation to the number of non-nucleated erythrocytes that the metabolism of the former is obscured by that of the latter.

Stage Specific Expression Pattern of Alpha-Hemoglobin-Stabilizing-Protein (AHSP) Portrayed in Erythroblast Chronology

Methods and Protocols, 2020
During erythropoiesis, the molecular chaperone alpha-hemoglobin-stabilizing protein (AHSP) sequesters free alpha-hemoglobin (αHb) and prevents precipitation of excess αHb.

Importância clínica da dosagem de lactato e contagem de eritroblastos no sangue colhido no segmento placentário da veia umbilical para o diagnóstico de hipóxia-isquemia em prematuros Clinical value of lactate measurement and nucleated red blood cell counts in the placental segment of the umbilical vein of premature newborns for diagnosis of hypoxia-ischemia

Jornal de Pediatria, 2007
OBJETIVO: Determinar a validade clínica das dosagens de lactato e contagem de eritroblastos quando comparados com o excesso de bases (EB) em sangue do segmento placentário da veia umbilical de prematuros. MÉTODOS: foram colhidas amostras de 25 prematuros,
