| Outline of Final Research Achievements |
An external urethral sphincter is one of the important tissues for maintaining urinary continence. The decrease of muscle cell number in external urethral sphincter is suggested to be one of the causes of urinary incontinence and chronic inflammation accompanying aging may to affect the decrease.
We established a method to isolate muscle precursor cells with high purity from external urethral sphincter tissue and to generate differentiable immortalized human external urethral sphincter muscle. Moreover we showed that TNF-α, one of the inflammatory cytokines, suppressed muscle differentiation via p-38MAPK and PI3K/Akt signal transduction pathway reversed its effects. TNF-α inhibitors are expected to be one of the treatments for elderly urinary incontinence.
