COMPOSITION FOR TISSUE REGENERATION, METHOD OF PRODUCTION AND USES THEREOF

The invention describes a method for obtaining a composition for tissue regeneration, comprising the following steps: providing M2-macrophages, co-culturing the M2-macrophages with tissue-specific cells in serum free medium; and collecting the supernatant of the co-culture. The compositions obtained by this method are suitable in medicine regenerative treatments, since are able to regenerate injured tissue. These products are sterile cell-free physiological aqueous solutions that show specific tissue concentration patterns to provide optimal tissue-specific regenerative effects. The compositions of the invention may be stored for long periods cryopreserved or lyophilized until its use, avoiding any subsequent blood extraction from the cell-donor, being the stored growth factors and/or cytokines biologically active after long-term storage. Moreover, the compositions may be potentially applied in both autologous and allogenic treatments. 本发明描述了获得用于组织再生的组合物的方法，其包括以下步骤：提供M2型巨噬细胞，在无血清培养基中将M2型巨噬细胞与组织特异性细胞共培养；并收集共培养
