Adipose-derived stem cells (ASCs) could be differentiated into SC-like phenotype (dASC) sharing morphological and functional properties with SC, therefore representing a valid SC option. We’ve got previously shown that dASC express c-aminobutyric-acid receptors, which modulate their proliferation and neurotrophic potential, even though small is known in regards to the function of other neurotransmitters in ASC.PMID:33416020 In this study, we investigated the expression of purinergic receptors in dASC. Applying reverse transriptase (RT)-PCR, western blot analyses and immunocytochemistry, we have demonstrated that ASCs express P2X3, P2X4 and P2X7 purinoceptors. Differentiation of ASCs towards glial phenotype was accompanied by upregulation of P2X4 and P2X7 receptors. Employing Ca2 ?-imaging strategies, we’ve got shown that stimulation of purinoceptors with adenosine 50 -triphosphate (ATP) triggers intracellular Ca2 ?signals, indicating functional activity of these receptors. Whole-cell voltage clamp recordings showed that ATP and BzATP induced ion currents that can be totally inhibited with precise P2X7 antagonists. Finally, employing cytotoxicity assays we’ve got shown that the increase of intracellular Ca2 ?results in dASC death, an impact that may be prevented applying a certain P2X7 antagonist. Altogether, these outcomes show, for the very first time, the presence of functional P2X7 receptors in dASC and their link with essential physiological processes including cell death and survival. The presence of these novel pharmacological targets in dASC could open new opportunities for the management of cell survival and neurotrophic possible in tissue engineering approaches working with dASC for nerve repair.
