Abstract The present invention provides a method of producing a cell population enriched for osteoclasts in which bone marrow mononuclear cells (BMNC) are cultured in a medium supplemented with growth factors, cytokines, or a combination thereof for at least 7 days to obtain colony-forming units of granulocytes and macrophages (CFU- GM); CFU-GM are isolated from culture by centrifugation; and isolated CFU-GM are cultured for a period of time and under conditions sufficient for CFU-GM to differentiate to osteoclasts. The invention further provides a cell population produced by the methods described. L'invention concerne un procédé permettant de produire une population cellulaire enrichie pour permettre la production d'ostéoclastes, consistant à mettre en culture des mononucléaires de la moelle osseuse (BMMC) dans un milieu enrichi par un apport de facteurs de croissance, de cytokines, ou d'une combinaison de ceux-ci pendant au moins 7 jours afin d'obtenir des cellules souches unipotentes/lignée granulocyto-monocytaire (CFU- GM). Ces CFU-GM sont isolées de la culture par centrifugation; et les CFU-GM sont mises en culture pendant une durée, et dans des conditions permettant leur différenciation en ostéoclastes. L'invention concerne en outre une population cellulaire produite au moyen de ces procédés.
