Abstract (original English)
Introduction Peyronie's disease (PD) has frequently been associated with erectile dysfunction (ED) and may further compromise coitus. Aim To investigate the efficacy of intratunical injection of genetically modified rat adipose tissue-derived stem cells (ADSCs) expressing human interferon α-2b (ADSCs-IFN) in decreasing fibrosis and restoring erectile function in a rat model of tunica albugineal fibrosis (TAF). Methods A total of 36 Sprague-Dawley rats (12 weeks old; 300-350 g) were randomly divided in six equal groups: (i) sham group (50 μL saline-injected into the tunica albuginea [TA]); (ii) TAF group (transforming growth factor [TGF]-β1 [0.5 μg/50 μL] injected into the TA); (iii) TGF-β1 plus 5 × 10(5) control ADSCs injected same day; (iv) TGF-β1 plus 5 × 10(5) ADSCs-IFN injected same day; (v) TGF-β1 plus 5 × 10(5) control ADSCs injected after 30 days; and (vi) TGF-β1 plus 5 × 10(5) ADSCs-IFN injected after 30 days. Rat allogeneic ADSCs were harvested from inguinal fat tissue. Main outcome measures Forty-five days following the TGF-β1 injection, erectile function was assessed, and penile tissues were harvested for further evaluations. Results In the same-day injection groups, intratunical injection of ADSCs and ADSC-IFN improved erectile response observed upon stimulation of cavernous nerve compared with TAF group. Intratunical ADSC-IFN injection at day 30 improved erectile r
