Analyses of collagen fiber distributions for three regions (central, CT; long arm, LA; and short arm, SA) of strip biaxial stretched gels on days 0, 3, and 6 (A). NLOM images were acquired from gels while stretched. Normalized AI to day 0 in the three regions for days 3 and 6 (B). Error bars are standard errors. Significant differences (p < 0.05) are denoted by asterisks.
