FIG. 7.

Pressure versus strain analysis of representative LV3 and LX vascular constructs. (A) LV3 constructs are slightly more elastic at low strains (0–12%) and fail at much higher pressures than LX constructs cultured under similar conditions. (B) LX constructs cultured in the absence of ascorbate had significantly decreased elasticity and increased burst pressure compared with LX constructs cultured in the presence of ascorbate. (C) LV3 constructs cultured in the absence of ascorbate are slightly more elastic at low strains and have higher burst pressures than LV3 constructs exposed to ascorbate. In (A–C), the standard deviations of the measurements were very small (2% or less); therefore, error bars are not shown for the sake of clarity.
