Data on nitric oxide production by human bone marrow-derived mesenchymal stromal cells.

Due to its anti-inflammatory and immunosuppressive potential, Nitric oxide (NO), a gaseous radical, is of special importance during graft-versus-host diseases (GVHD) and feoto-maternal tolerance. NO is a major mediator of murine mesenchymal stromal cells (MSCs)-immunosuppressive capacity. In this data article, we characterized NO production by human bone marrow-derived MSCs (hBMSCs). MSCs, isolated from healthy donors (n=5), were defined according to the International Society for cellular Therapy (ISCT) guidelines. Based on a fluorometric detection system, and upon using Nitrite ([Formula: see text])/Nitrate ( [Formula: see text]) Assay Kit, the amounts of NO metabolites ( [Formula: see text] and [Formula: see text]) produced by hBMSCs, being grown in a culture medium either lacking (constitutive condition) or containing IL-4, IL-10 or a pro-inflammatory cytokine cocktail made of IL-1β, TNF-α, IFN-α and IFN-γ, were assessed. All assays were carried out in triplicates and the mean values are reported. The data from this study supports and corroborates the discussion associated with our previously published work entitled "The Immunomodulatory Potential of Mesenchymal Stromal Cells: A Story of a Regulatory Network" (Najar et al., 2016) [1].
