27. A method for the manufacture of implantable substrates for the healing and/or protection of connecting tissue, said substrate comprising:
-
a composition comprising biologically active factors (i), (ii), and (iii), wherein (i) is a growth and differentiating factor, (ii) is a chemotactic factor, and (iii) is a cellular adhesion molecule; and
at least one structure for cell invasion in vivo and/or for the formation of cell matrix and/or for the release of constituents of the employed composition, wherein said structure comprises at least one constituent (a) to (f);
(a) a hydrogel, (b) a compound selected from the group consisting of sponges, collagen sponges, (c) a compound selected from the group consisting of wool, a cotton wool-like structure, wool made of polysaccharides, cellulose wool, and cellulose cotton wool, (d) a compound selected from the group consisting of natural or synthetic polypeptides, fibrin, and polylysine, (e) a compound selected from the group consisting of plaitings, knitted fabrics, woolen structures made of fibers, and fibers comprising resorbable polymers, (f) a compound selected from the group consisting of cement pastes, acrylate cements, bonding sheets, and fibrinogen-covered hyaluronic acid foil, comprising at least one of the following steps;
(i) bringing said structure into contact with at least said above defined composition or (ii) bringing said biologically active factors (i), (ii), and (iii) of said composition into contact with said above defined structure. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34)
