[Stem cells for the treatment of Peyronie's disease]

Abstract

Peyronie's disease (PD) is a connective tissue disorder characterized as fibrotic plaque localized in the tunica albuginea (TA), and its pathomechanism remains obscure. Endeavors are being made to explore effective and minimally invasive therapeutic strategies for PD, and some experimental studies have verified the preventative and therapeutic effects of stem cells (SC), especially adipose tissue-derived SCs (ADSC), on this disease and excavated some of their action mechanisms. Some scholars attempted the integration of SCs with graft tissues, aiming at the improvement of TA grafting and reconstruction. The only publicly available clinical trial of SC therapy for PD was encouraging, and further on-coming relevant researches are expected with simultaneous optimization of the scheme. In a word, the application of SCs in the prevention and treatment of PD is a promising topic for clinical research, and there remain quite a lot of unknowns to be explored. This article summarizes the existing researches in this field.
