New concepts in regenerative medicine approaches to the treatment of female stress urinary incontinence.

Abstract:

PURPOSE OF REVIEW:Update on recent regenerative medicine approaches to the treatment of stress urinary incontinence (SUI) caused by intrinsic sphincter deficiency (ISD). RECENT FINDINGS:In the treatment of female SUI/ISD, results using different types of cellular therapy have been disappointing, and new approaches are desirable. To advance our regenerative medicine approaches to SUI/ISD, it is critical to utilize animal models that best parallel the pathophysiology of this disease in women. Many current animal models mimic acute SUI/ISD. However, SUI/ISD in women is usually a chronic condition resulting from previous muscle and nerve sphincter damage during parturition or muscle loss during aging. Similar to women, a nonhuman primate (NHP) model of chronic SUI/ISD has demonstrated only modest response to cell therapy. However, treatment with stromal cell-derived factor 1 (SDF1), also known as C-X-C motif chemokine 12 (CXCL12) restored continence in this model. SUMMARY:As a potential therapeutic approach, the use of a well characterized chemokine, such as CXCL12, may by-pass the lengthy and expensive process of cell isolation, expansion, and injection. Recent findings in this new NHP model of chronic SUI/ISD may open up the field for noncell-based treatments.
