Concentrations of ethanol similar to those in the blood of intoxicated patients suppressed phytohemagglutinin- or streptolysin O-induced lymphocyte transformation, and inhibited bone marrow granulocyte colony growth in soft agar. Inhibition of lymphocyte transformation and granulocyte colony growth occurred despite the presence of large concentrations of folate and other vitamins. These in vitr...

Fetal mouse liver cultures capable of producing both erythropoietin (Ep) and granulocyte-macrophage colony stimulating activity (GM-CSA) were used to study the specificity of lactoferrin as an inhibitor of the production of GM-CSA. Both a granulocyte-derived colony-inhibiting activity (CIA) and lactoferrin inhibited GM-CSA production while having no effect on Ep production. These results demons...

We have studied the sensitivities of four hematopoietic stem cell types to heat stress as well as their abilities to develop thermotolerance. Granulocyte-macrophage colony forming units were the most heat resistant bone marrow progenitors tested. Of the erythroid progenitors tested, erythrocyte colony forming units were more resistant than the two more primitive erythrocyte burst forming units....

Human bone marrow cells cultured for 21 days in the presence of recombinant human interleukin-3 (IL-3) produced up to 28 times more colony-forming cells (CFC) than could be obtained from cultures stimulated with granulocyte colony stimulating factor (G-CSF) or granulocytemacrophage CSF (GM-CSF). 11-3-cultured cells retained a multipotent response to 11-3 in colony assays but were restricted to ...

The biotechnology industry has established itself as a major source of new human therapeutic protein drugs which can be described as complex biological entities. The majority of these in production, such as erythropoeitin (EPO), interleukin-2 (IL-2), interferon (IFN), granulocyte colony stimulating factor (G-CSF), granulocyte macrophage-colony stimulating factor (GM-CSF) and tissue plasminogen ...

The effects of transforming growth factor flu or (TGF-/11 or -p2) on the in vitro proliferation and differentiation of normal and malignant human hematopoietic cells were studied. Both forms of TGF-fl suppressed both the normal cellular proliferation and colony formation induced by recombinant human interleukin-3 (IL-3) and granulocyte-macrophage colony-stimulating factor (GM-CSF). In the prese...
