We examined the effect of human recombinant granulocyte-colony stimulating factor (G-CSF) on the release of immunoreactive endothelin-1 (ET-1) from cultured bovine vascular endothelial cells. G-CSF dose dependently (10(-8)-10(-6) M) increased the release of immunoreactive ET-1 as a function of time under a serum-free condition. Coaddition of G-CSF and thrombin induced an additive effect on immunoreactive ET-1 release. Neither Ca2+ channel antagonist nor cyclooxygenase inhibitor affected immunoreactive ET-1 release stimulated by G-CSF. These results suggest that G-CSF, in addition to its effect on granulocyte progenitors, has a direct effect on vascular endothelium to induce the release of immunoreactive ET-1.

D004727 Endothelium A layer of epithelium that lines the heart, blood vessels (ENDOTHELIUM, VASCULAR), lymph vessels (ENDOTHELIUM, LYMPHATIC), and the serous cavities of the body. Endotheliums
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D016179 Granulocyte Colony-Stimulating Factor A glycoprotein of MW 25 kDa containing internal disulfide bonds. It induces the survival, proliferation, and differentiation of neutrophilic granulocyte precursor cells and functionally activates mature blood neutrophils. Among the family of colony-stimulating factors, G-CSF is the most potent inducer of terminal differentiation to granulocytes and macrophages of leukemic myeloid cell lines.

D016232 Endothelins 21-Amino-acid peptides produced by vascular endothelial cells and functioning as potent vasoconstrictors. The endothelin family consists of three members, ENDOTHELIN-1; ENDOTHELIN-2; and ENDOTHELIN-3. All three peptides contain 21 amino acids, but vary in amino acid composition. The three peptides produce vasoconstrictor and pressor responses in various parts of the body. However, the quantitative profiles of the pharmacological activities are considerably different among the three isopeptides.
