Figure 3From: The feasibility of ureteral tissue engineering using autologous veins: an orthotopic animal model with long term results Average shortening of the ureteral patch (in cm) after 12, 24, and 48 weeks (tissue engineered vs. control). The average shortening of the length of the graft was higher in the animals with unseeded grafts when compared to tissue engineered scaffolds (1.7 cm versus 1.0 cm).Back to article page
