Abstract (original English)
Aim Stress urinary incontinence (SUI) is a significant health problem for women. Treatments employing muscle derived stem cells (MDSCs) may be a promising approach to this prevalent, bothersome condition, but these treatments are invasive and require collection of cells from one site for injection into another. It is also unknown whether or not these cells establish themselves and function as muscle cells in the target tissues. Alternatively, low-intensity extracorporeal shock wave therapy (Li-ESWT) is non-invasive and has shown positive outcomes in the treatment of multiple musculoskeletal disorders, but the biological effects responsible for clinical success are not yet well understood. The aim of this study is to explore the possibility of employing Li-ESWT for activation of MDSCs in situ and to further elucidate the underlying biological effects and mechanisms of action in urethral muscle. Methods Urethral muscle derived stem cells (uMDSCs) were harvest from Zucker Lean (ZUC-LEAN) (ZUC-Leprfa 186) rats and characterized with flow cytometry. Li-ESWT (0.02 mJ/mm 2 , 3 Hz, 200 pulses) and GSK2656157, an inhibitor of PERK pathway, were applied to L6 rat myoblast cells. To assess for myotube formation, we used immunofluorescence staining and western blot analysis in uMDSCs and L6 cells. Results The results indicate that uMDSCs could form myotubes. Myotube formation was significa
