We tested the capabilities of drugs elevating extracellular adenosine and of granulocyte colony-stimulating factor (G-CSF), given alone or in combination, to mobilize haematopoietic progenitor cells for granulocytes and macrophages (GM-CFC) and granulocytes into peripheral blood. Elevation of extracellular adenosine was induced by joint administration of dipyridamole (DP), a drug inhibiting the cellular uptake of adenosine, and adenosine monophosphate ( AMP) serving as an adenosine prodrug. DP + AMP, G-CSF or all these drugs in combination were administered either singly or repeatedly in a 4-d treatment regimen. Elevation of extracellular adenosine was found to mobilize significantly both GM-CFC and granulocytes after both single and repeated administration of DP + AMP. These results show that the elevation of extracellular adenosine presents a potent mechanism for mobilization of GM-CFC and granulocytes into the blood.
