The pharmacological activation of adenosine A1 and A 3 receptors does not modulate the long- or short-term repopulating ability of hematopoietic stem and multipotent progenitor cells in mice.

ABSTRACT: This study continues our earlier findings on the hematopoiesis-modulating effects of adenosine A1 and A3 receptor agonists that were performed on committed hematopoietic progenitor and precursor cell populations. In the earlier experiments, N (6)-cyclopentyladenosine (CPA), an adenosine A1 receptor agonist, was found to inhibit proliferation in the above-mentioned hematopoietic cell systems, whereas N (6)-(3-iodobenzyl)adenosine-5'-N-methyluronamide (IB-MECA), an adenosine A3 receptor agonist, was found to stimulate it. The topic of this study was to evaluate the possibility that the above-mentioned adenosine receptor agonists modulate the behavior of early hematopoietic progenitor cells and hematopoietic stem cells. Flow cytometric analysis of hematopoietic stem cells in mice was employed
