Quantitative analysis of SMA, vWF staining area. Expression levels of cavernous endothelial and smooth muscle makers were increased in the groups with transplantation of HEN6 than the cavernous nerve-injured group. The number of rats used in the study was 6 for each study interval and group. *P < 0.05 (Sham Vs CNI, CNI Vs 2 weeks, CNI Vs 4 weeks, CNI Vs 12 weeks). SMA = smooth muscle actin, vWF = von Willebrand factor, HEN6 = human telomerase reverse transcriptase immortalized cerebral endothelial progenitor cells
