摘要
Our goal was to determine whether periuirethral injection of allogenic muscle-derived stem cells (MDSC) Could increase the leak point pressure (LPP) in a denervated female rat model of stress urinary incontinence. Cells isolated from the gastrocnemius muscle of normal female rats were purified for a myogenic population by the preplate technique. Three experimental groups were established: a control group (C) had a sham operation without Injections; a sciatic nerve transection Group (D) had periurethral saline injections; and a sciatic nerve transsection group had periurethral MDSC injections (M). One week following treatment the LPP of groups C, D and M were 25.2 +/- 1.9 cmH(2)O, 28.6 +/- 0.8 cmH(2)O and 36.7 +/- 2.3 cmH(2)O respectively. At 4 weeks the LPP of groups C, D and M were 25.8 +/- 2.5 cmH(2)O, 18.6 +/- 5.2 cmH(2)O and 44.1 +/- 6.6 cmH(2)O, respectively. Allogenic MDSC significantly improved the LPP in sciatic nerve-transected animals after both 1 and 4 weeks compared to denervated animals injected with saline.
