FIG. 5.

Macroscopic inspection of retrieved urethra at 2 weeks, 1 month, 2 months, and 6 months postimplantation. Excessive scarring and contracture of the urethral lumen at operative site was observed in the BAMG group at 2 weeks postimplantation, followed by progressive fibrosis in the next several months. Similar contracture and fibrosis was observed in the Und-rASCs/BAMG group soon after the surgery, which improved slightly by 2 months postimplantation. In the Epith-rASCs/BAMG group, a mild contracture of the urethral lumen was observed at 2 weeks postimplantation, which was markedly improved at 2 and 6 months postimplantation. Arrow indicates the replaced part of urethra. Color images available online at www.liebertpub.com/tea
