Topic: Erythropoiesis


  
  UMDNJ Research Fall 2004--Adrenergic modulation of erythropoiesis following trauma
Erythropoiesis and the formation of red blood cells is a complex process involving bone marrow stem cells, progenitor cells, and stromal cells.
It is the impact of this stress or "adrenergic state" on erythropoiesis and its subsequent dysfunction that is the focus of my research.
Adrenergic modulation of erythropoiesis is known to occur under normal conditions and typically red blood cell growth is enhanced.

 BioMed Central | Full text | Neonatal erythropoiesis and subsequent anemia in HIV-positive and HIV-negative Zimbabwean ...
For the present study, we used a model of the relationships between indicators of iron status and erythropoiesis (Figure 1) to guide our examination of erythropoiesis in young infants and the impact of HIV infection on the process.
Transferrin receptors (TfRs) present on the surface of erythroid cells increase with the expansion of the erythroid mass, and a soluble truncated form of the tissue receptor increases proportionally in the serum [15-17].
A noteworthy effect of HIV infection on erythropoiesis was the modification of infant infection on the association between ferritin and TfR at 6 months of age.

Efficient stress erythropoiesis in response to 5-fluorouracil, hemolytic anemia, or bone marrow transplantation is not supported by a minimal PY-null EpoR-HM allele but is rescued by EpoR-H–PY343–Stat5 signals.
The distal region and receptor tyrosines of the Epo receptor are non-essential for in vivo erythropoiesis.

  Sickle-cell disease - Wikipedia, the free encyclopedia
An acute worsening of the patient's baseline anemia producing pallor, tachycardia, and fatigue.
This crisis is triggered by parvovirus B19, which directly affects erythropoiesis (production of red blood cells).
Reticulocyte counts drop dramatically during the illness and the rapid turnover of red cells leads to the drop in hemoglobin.

 Insulin-Like Growth Factor I Stimulates Erythropoiesis in Hypophysectomized Rats -- Kurtz et al. 85 (20): 7825 -- ...
Stimulation of erythropoiesis during growth is necessary to ensure proportionality between erythrocyte mass and body mass.
Growth arrest in hypophysectomized rats is accompanied by decreased erythropoiesis.
They also show that IGF-I can stimulate erythropoiesis in an endocrine manner, and they suggest two possible routes of action: a direct one and an indirect one by means of enhanced erythropoietin production.

 Introduction: Anemias Caused by Deficient Erythropoiesis: Merck Manual Professional
Anemias due to decreased erythropoiesis are recognized by reticulocytopenia, which is usually evident on the peripheral blood smear (see Approach to the Patient With Anemia: Testing).
The RBC indices, mainly the MCV, narrow the differential diagnosis of deficient erythropoiesis and determine what further testing is necessary.
Because erythropoiesis increases the iron requirement, supplemental iron is helpful when administering any type of treatment that aims to increase erythropoiesis.
