Outline of Final Research Achievements

Hirschsprung's disease and its variants are known as disorders with intestinal peristaltic dysfunction developed from childhood. Congenital Hypoganglionosis (Hypo) is a representative disease of the variants with few intestinal ganglion cells. Currently, the patients are treated with bowel resection and enterostomy palliatively. Unfortunately, the survival rate show 78%, and the patients are hard to withdraw intravenous nutrition after the surgery. Small bowel transplantation is the only curative treatment for the patients; however, it is hard to perform in Japan, because of varied problems such as severe immune rejection and expensive cost resulting in severe outcomes.
Therefore the alternative therapeutics has been desired. Recently, stem cell-based regenerative therapy has been focused on a variety of refractory diseases. Currently, we transplanted stem cells into Hypo model mice, and improved the phenotype, pathological findings and electrophysiological motility.
