<p>A) The penises were isolated for protein extraction 2 weeks after the AdGFP_HUVECs injection, and 2 (2W), 4 (4W), and 6 (6W) weeks after the AdRas12V_HUVECs injection. Proteins were also extracted from age-matched control mice (Control). Representative photographs are shown. B) Histograms showing the relative intensity of the bands (n = 4 per group). * and **: P<0.05 and P<0.01, respectively vs. AdGFP_HUVECs injection. T-eNOS: total eNOS.</p
