FIG. 4.

TEVG mechanical properties and composition after 8 and 24 weeks. Comparison of (a) wall thickness, (b) ultimate tensile strength (UTS), (c) modulus, (d) anisotropy index, (e) collagen concentration, and (f) cell concentration in fresh femoral artery (Native, n=3) and 8-week sham control (Control, n=3) in comparison to TEVG before implantation (Preimplant, n=3) and after 8 weeks ( n=5) and 24 weeks (n=3) of implantation. Statistical difference at p<0.05 between properties is shown with paired symbols. Color images available online at www.liebertpub.com/tea
