FIG. 5.

Quantification of CD31 stained cross sections from various tissue regions. (A) At day 11, lumen density was increased in the middle region over the inlet and outlet regions. However, even when all of the data were combined, the increase in lumen density with low flow remained. (B) Average lumen diameter at day 11 did not vary by tissue region, but was larger in constructs exposed to low flow. (C) No differences in PC recruitment occurred between regions or flow conditions at day 11. (D) At days 5 and 8, no differences in lumen density occurred across tissue regions. *p<0.05 for main effects. ^$p<0.05 for main effects between control and low flow. ⁺p<0.05 for main effects between low and high flow.
