FIG. 3.

Comparison of quantitative morphometric analysis of tissue-engineered vascular grafts (TEVG). (A) Representative scanning electron microscope images of scaffolds before cell seeding. (B) Representative hematoxylin and eosin (HE) staining images of patent and occluded TEVG. (C) The adventitia, media, and intima were manually identified and measured on HE staining, and patent was defined as greater than 50% in luminal diameter compared to graft at time of implantation. There was no statistical difference in patency of grafts at 2 weeks between the groups. Data were evaluated by Fisher's exact test. (D) Neither luminal diameter nor neointimal thickness differed between groups. Data were evaluated by Welch's t test. Color images available online at www.liebertpub.com/tec
