Adipose-derived-stem-cells (ADSC) have shown promise in treating
erectile dysfunction (ED). Here we investigated the effect of ADSC
engraftment in restoring erectile function (EF) following nerve injury
during radical prostatectomy. Sprague-Dawley rats (4 groups; n=8/
group) underwent: 1) laparotomy (Lap) and immediate closure
(Sham); 2) Lap with bilateral cavernosal nerve injury (BCNI) (Crush);
3) Lap with BCNI and intracavernosal injection (ICI) of GFP+-ADSC
at surgery (INJ-1); and 4) Lap with BCNI and ICI of GFP+-ADSC
twice (at surgery and after three weeks) (INJ-2). Six weeks postBCNI, EF was measured via intracorporal pressure (ICP) response
following cavernosal nerve stimulation at 2.5V, 5V, and 7.5V. Penile
