found application in regeneration of bone defects, peripheral nerves and the engineering of cardiac-tissue. Gel is a collagen derivative, obtained after its partial hydrolysis and breakdown of the naturally occurring triple helix into small peptide fragments. During this process the material loses its biological activity but retains its biocompatibility and cell adhesion motifs such as the arginine-glycine-aspartic acid (RGD) sequence. Compared with the starting material, the individual molecules are much easier to modify. The reaction with methacrylic anhydride (MA)
