Salmon-derived fibrin has been proposed as a preferred alternative to human or bovine fibrin because of its reduced potential for disease transmission. Here we evaluate salmon fibrin as an alternative ECM support for therapeutic angiogenesis applications, such as vascularizing engineered tissues. Human umbilical vein endothelial cells (HUVEC) seeded on gelatin beads and suspended in either salmon or human fibrin sprouted and formed capillary-like structures. Sprout length was generally increased with the addition of bFGF and VEGF and further increased with the addition of phorbol myristate acetate (PMA). The number of sprouts per bead was increased 61-188% in salmon fibrin relative …
