Alteration of adipokines during peripheral blood stem cell mobilization induced by granulocyte colony-stimulating factor.
2009
Adipokines, soluble mediators produced by adipocytes, have been shown to play a role in various physiological and pathological conditions. We investigated the involvement of adipokines in granulocyte colony-stimulating factor (G-CSF)-induced mobilization of hematopoietic stem cells in 21 healthy donors. We found that serum visfatin and resistin levels, but not leptin and adiponectin levels, were significantly elevated by G-CSF treatment. G-CSF treatment activated signaling proteins like extracellular signal-regulated kinase and stimulated secretion of visfatin from 3T3-L1 adipocytes. These findings suggest that some adipokines may play a role in G-CSF-induced mobilization of stem cells from the bone marrow into systemic circulation. J. Clin.
