Abstract
A stable injectable collagen-based hydrogel delivery platform and method is provided to obtain the viscosity, post-injection stability and mechanical properties needed of an injectable collagen matrix via incorporating alginate and calcium sulfate (CaSO) into the matrix. The hydrogel (Alg/Col hydrogel) is shear-thinning, injectable through commercially available needles and stable right after injection.
