摘　　要：In our previous study,we showed that with increasing time in culture,the growth characteristics of enteric neural crest-derived cells(ENCCs)change,and that the proliferation,migration and neural differentiation potential of these cells in vitro notably diminish.However,there are no studies on the developmental differences in these characteristics between fetal and early-postnatal stages in vitro or in vivo.In this study,we isolated fetal(embryonic day 14.5)and postnatal(postnatal day 2)ENCCs from the intestines of rats.Fetal ENCCs had greater maximum cross-sectional area of the neurospheres,stronger migration ability,and reduced apoptosis,compared with postnatal ENCCs.However,fetal and postnatal ENCCs had a similar differentiation ability.Fetal and postnatal ENCCs both survived after transplant into a rat model of Hirschsprung’s disease.In these rats with Hirschsprung’s disease,the number of ganglionic cells in the myenteric plexus was higher and the distal intestinal pressure change was greater in animals treated with fetal ENCCs compared with those treated with postnatal ENCCs.These findings suggest that,compared with postnatal ENCCs,fetal ENCCs exhibit higher survival and proliferation and migration abilities,and are therefore a more appropriate seed cell for the treatment of Hirschsprung’s disease.This study was approved by the Animal Ethics Committee of the Second Affiliated Hospital of Xi’an Jiaotong University(approval No.2016086)on March 3,2016.
