Cellular therapy with polarized macrophages for tissue regeneration

摘要

The invention provides an in vitro method for inducing macrophage polarization to an M2 phenotype useful for tissue repair. The method described in the present invention comprises the in vitro exposure of macrophages to repeated series of hypoxia-reoxygenation. Activated M2 macrophages obtained by this method overexpress molecules important for tissue remodeling and amelioration of inflammation, such as NGAL and antiinflammatory cytokines (IL-10). Thus, M2 macrophages obtained by this method are useful as cell therapy for tissue regeneration. The invention also provides pharmaceutical compositions and kits comprising the M2 macrophages obtained by the described method.
