FIG. 10.

Histological scoring of vasculature, collagen, and residual polymer. To determine vasculature, four representative fields of inflamed tissue were examined at 40× and vessel cross sections containing erythrocytes were counted. Collagen was scored by assessing if no collagen was present (1), few collagen fibrils present (2), and many collagen fibrils present (3). The amount of polymer present was ranked from no polymer (0), 25% (1), 50% (2), 75% (3), and 100% of polymer present (4) (@ significantly higher quantity of vasculature than other groups [and AE] within the TGF-β3 group [p<0.05], # and $ significantly higher quantity of vasculature than nonfatal cases within their respective groups [p<0.05]).
