Concentric rings analysis to determine vascular distribution within 7 day implants. (a) Representative image showing concentric rings and centroid used for analysis. 1 = Outer ring; 2 = Middle ring; 3 = Inner ring. Average number of RECA-1+ lumen structures within each ring for unmodified and aprotinin scaffolds in (b) midpoint sections and (c) distal end sections. * Indicates statistical significance from corresponding ring in unmodified scaffolds (Student’s t-test, p < 0.05). Scale bar = 500µm.
