...Vincent S. Gallicchio; Martin J. Murphy, Jr. The cardiac glycoside ouabain has been shown to stimulate erythroid stem cell (CFU-e/BFU-e) colony formation while inhibiting both granulocyte/macrophage precursor cell (CFU-gm) and murine spleen stem cell (CFU-s) colony formation. We have examined...

...Dominick Amato; Nasim R. Khan We have studied the growth of erythroid bursts in methylcellulose cultures from bone marrow (7 cases) and peripheral blood cells (17 cases) of patients with primary acquired refractory anemias. In most cases, erythroid burst-forming units (BFU-E) were either absent...

... in a micro agar culture system several times over a period of 11 months, revealing a diminished frequency of bone marrow erythroblasts paralleled by a markedly reduced number of CFU-e and BFU-e in vitro. No inhibitory activity in the patient’s IgG fraction could be detected either by preincubation with IgG...

... and released an activity that stimulated normal BFU-E growth. This patient demonstrates that immature T cells may modify hematopoietic stem cell growth both in vitro and in vivo. 5 11 1987 26 02 1988 24 2 2009 © 1988 S. Karger AG, Basel 1988 Copyright / Drug Dosage / Disclaimer...

...L. Morra; A.G. Ponassi; G. Gurreri; F. Moccia; G.S. Mela; F. Boglioio; P. Beltrami; C. Sacchetti The growth of normal burst-forming units (BFU-E) is known to depend on a burst-promoting activity (BPA) produced by T-lymphocytes. Few BFU-E colonies have been observed in cultures of blood mono-nuclear...

... phytohemagglutinin-stimulated leukocyte-conditioned medium as an exogenous source of Meg-CSA. Increased megakaryocyte numbers and resultant thrombocytosis in PV are likely based on the abnormal population of CFU-Meg. 30 12 1986 11 05 1987 24 2 2009 BFU-E CFU-Meg Marrow megakaryocytes...

...L. Morra; A. Ponassi; F. Moccia; G.S. Mela; I. Ponassi; G. Bessone Glucocorticosteroid hormones have been reported either to stimulate or to inhibit human erythropoiesis. We have studied the in vitro effect of hydrocortisone, 10 -6 mol/l, on human BFU-E when stimulated by preconstituted burst...

...N.G. Abraham; A. Mathew; S. Jiang; J.D. Lutton; M. Nishimura; J.L. Chertkov; R.D. Levere The ability of peripheral-blood hematopoietic progenitor cells from AIDS patients and normal controls to respond to erythropoietin (Epo) was assessed for burst-forming units-erythroid (BFU-E). BFU-E colony...

...S. Moqattash; J.D. Lutton; M.F. Abu-Hijleh; N.G. Abraham We studied the toxic effects of azidothymidine (AZT) on the hemopoietic colony growth (CFU-E, BFU-E and CFU-GM) of bone marrow in a murine model of AIDS (MAIDS). A sparing effect by recombinant hemoglobin (r-Hb) on AZT suppression of MAIDS...

...-E. The CD34+ cell concentrations per sample tended to be greater at an ANC <1,000 mm 3 and decreased with rising ANC (p = 0.001). The CFU-GM and BFU-E concentrations per sample remained relatively constant with rising ANC (p = 0.72, p = 0.90, respectively). Total CD34+ cell number per harvest per...
