Quantification of in vitro and in vivo angiogenesis stimulated by ovine forestomach matrix biomaterial.

Ovine forestomach matrix (OFM) biomaterial acts as a biomimetic of native extracellular matrix (ECM) by providing structural and functional cues to orchestrate cell activity during tissue regeneration. The ordered collagen matrix of the biomaterial is supplemented with secondary ECM-associated macromolecules that function in cell adhesion, migration and communication. As angiogenesis and vasculogenesis are critical processes during tissue regeneration we sought to quantify the angiogenic properties of the OFM biomaterial.
