Abstract

Stem cell is characterized with self-renewal and mult-potency. Many pediatric gastrointestinal diseases have defect in enterocytes, enteric nervous system, and Interstitial cell of Cajal. Various kinds of stem cell could be applied to these diseases. Here, the author introduces stem cell for pediatric gastrointestinal diseases, particularly Hirschsprung disease.

Keywords: Stem cell; Hirschsprung disease

Fig. 2
Neurons from transplanted neurospheres regulate the contractility of developing gut. EMNS and NHNS transplanted bowel have comparable contraction frequencies to ganglionic distal colon, but have significantly lower contraction frequencies than aganglionic distal colon, demonstrating a functional effect of neurosphere transplantation18). EMNS: aganglionic distal colon transplanted with embryonic mouse neurosphere, NHNS: aganglionic distal colon transplanted with neonatal human neurosphere, TTX: tetrodotoxin.
