Tissue-engineered blood vessel (TEBV) support bath extrusion optimization and TEBV sizes. TEBVs extruded with collagen concentration of 10 mg/mL in (A) gelatin microparticles or (B) in cell culture media, with 25 mL/h as the injection speed. (C) Size of outer diameter, inner diameter and wall thickness depending on the injection speed with collagen at 10 mg/mL and 20 mg/mL. Data represented as mean with standard deviation (n = 8 per condition). * Statistically significant differences between the two collagen concentrations for the same injection speed (p < 0.05).
