Abstract: Methods for the identification and isolation of multipotent cells from non-osteochondral mesenchymal tissue. Specifically, this invention relates to an adult multipotent cell or a cell population or composition comprising said cell, isolated from non-osteochondral mesenchymal tissue, characterized in that the cell is positive for the following markers: CD9, CD10, CD13, CD29, CD44, CD49A, CD51, CD54, CD55, CD58, CD59, CD90 and CD105 and because it lacks expression of the following markers: CD11b, CD14, CD15, CD16, CD31, CD34, CD45, CD49f, CD102, CD104, CD106 and CD133.

Abstract: A biomaterial for suturing comprising a physiologically compatible support material coated with a cellular population with proliferative and/or differentiation capacity, characteristics which facilitate the regeneration of the sutured tissue. This biomaterial for suturing not only brings together the two edges of an open wound, but also contributes actively to the healing process, thereby accelerating the tissue repair process. Also disclosed are methods for making the biomaterial and methods for using the biomaterials in therapy.
