Functional External Anal Sphincter Reconstruction for Treatment of Anal Incontinence Using Muscle Progenitor Cell Auto Grafting

Abstract

Transplanting muscle progenitor cells showed the potential for recapitulation of a myogenic program when injected into deficient rabbit anal sphincter. Objective anal measures of resting and stimulated pressures and electromyographic profile improved. Stem cell-mediated anal myoplasty warrants additional investigation as a new method to treat anal incontinence before attempting this modality in the clinical setting.
