Abstract

Nitric oxide is an endogenous gas which exerts autocrine/paracrine actions by different signaling pathways and/or direct interactions with intracellular compounds and structures. Several processes are regulated by nitric oxide in stem cells including self-renewal, viability, migration, proliferation, and differentiation. The modulation of cell functions depends on its concentrations because opposite effects can be observed when low and high levels of nitric oxide are compared. Here, the responses to nitric oxide of adult stem/progenitor cells which are often used in regenerative medicine, including mesenchymal stem cells, hematopoietic stem cells, neural stem cells, endothelial progenitor cells, satellite cells, and fibro-adipogenic precursor cells, are reviewed. Therapeutic strategies which employ drugs releasing nitric oxide or modulating nitric oxide intracellular pathways are suggested to perform new ex vivo preconditioning or in vivo treatments suitable for stem/progenitor cell therapy and tissue engineering applications.
