Comparison of the mean number of CD31(+) vessels in the OT grafts after Ang2 treatment according to post-transplantation durations.

<p>The statistical difference was considered significant when the p value was <0.05 (control, no treatment of Ang2; 50 ng Ang2, injection of 50 ng/kg Ang2; 500 ng Ang2, injection of 500 ng/kg Ang2). Different superscript letters indicate statistically significant differences (p < 0.05), and the superscripts were used for each group of the same transplantation duration separately.
