The presence of heterogeneous erythroid progenitor cells, contaminant cells, or serum may
alter erythroid colony development in vitro. To obtain highly purified colony-forming units …

Morphological and biochemical studies of human colony-forming units-erythroid (CFU-E)
have been hindered by their extreme rarity. Since burst-forming units-erythroid (BFU-E) …

Recombinant human insulin-like growth factor I (IGF-I) increased human and murine
erythropoietic colony formation in serum-free culture. In order to investigate the effects of …

Abstract We have used 75% to 90% pure murine erythroid colony-forming units (CFU-E) to
delineate the processes and factors underlying their maturation. These CFU-E form 32 cell …

Erythropoietin (EP), insulin-like growth factor I (IGF-I) and stem cell factor (SCF) each reduce
apoptosis of human erythroid progenitor cells. To determine if these growth factors have …

We have found that the peripheral blood of normal humans contains a significant number of
committed erythroid stem cells of high proliferative capacity. These erythroid stem cells …

The effect of insulin on the proliferation of late stage erythroid precursor cells (CFU‐e) from
fetal mouse liver and aduit bone marrow was studied in a serum‐free culture system. Insulin …

The effect of pure human insulin‐like growth factor I (IGF I) on the colony formation of late
stage erythroid precursor cells (CFU‐e) from fetal mouse liver and adult bone marrow was …

Several culture media for the growth of human circulating erythroid burst-forming units (BFU-
E) that have been claimed to be “serum-free”(“SF”) have actually included albumin …

Erythroid progenitors (BFU-E) from adult human peripheral blood generate erythroid bursts
in semisolid culture supplemented with at least two growth factors, ie, erythropoietin (Ep) …
