Summary:The present invention relates to the isolation of human stem cells for use e.g. in cell therapy. More specifically, the invention is a method of separating mononuclear cells from human blood, which method comprises providing a human blood sample together with density gradient media (DGM) in a container; spinning the container comprising blood and DGM; and collecting the DGM fraction that comprises mononuclear cells; wherein the DGM has a density which is >1.080 and <1.090 g/cm3 as measured at 250C. The invention also relates to bags and tubes which contain density gradient media wherein the density and osmolality has been optimized for use in the present method, preferably as kits. L'invention porte sur l'isolation de cellules souches humaines notamment à des fins de thérapie cellulaire, et plus spécifiquement sur une méthode de séparation des cellules sanguines mononucléaires consistant: à placer dans un récipient un échantillon de sang et un média à gradient de densité (DGM); à centrifuger le récipient; et à recueillir la fraction de DGM contenant les cellules mononucléaires. La densité du DGM est >1,080 et <1,090 g/cm3 mesurée à 25°C. L'invention porte également sur des poches et tubes, de préférence sous forme de trousses, contenant du DGM dont la densité et l'osmolalité ont été optimisées pour la présente méthode.
