Induction of vascularization response by fibrin scaffold formulations. Average number of RECA-1+ lumen structures/mm2 within scaffolds at (a) 7 days and (b) 14 days post-implantation. Average number of RECA-1+ lumen structures/mm2 in an area of surrounding tissue on the skin side of implants at (c) 7 days and (d) 14 days post-implantation. * Indicates statistical significance from unmodified scaffolds (Student’s t-test, p < 0.05).
