Potential of Human Umbilical Cord Matrix and Rabbit Bone Marrow–Derived Mesenchymal Stem Cells in Repair of Surgically Incised Rabbit External Anal Sphincter

Abstract

Stem cell injection at the site of injury can enhance contractile function of the anal sphincter without surgical repair. Transplantation of stem cells, particularly bone marrow mesenchymal cells, may provide an effective tool for treating anal sphincter injuries in humans.
