FIGURE 6

Relative frequency of observation for the alignment of collagen fibrils in porcine engineered vessels (n = 8) and porcine carotid arteries (n = 2). φc is the angle shown in Fig. 1 (φc = 5 indicates that collagen is oriented circumferentially; φc = 45 indicates that collagen is oriented helically; φc = 85 indicates that collagen is oriented axially). The frequency of collagen in circumferential or axial alignments were significantly different (*, p < 0.05) between engineered and native vessels.
