Furthermore, PTU inhibited mitosis of ENCCs and reduced the number of enteric neurons throughout the larval zebrafish intestine. Importantly, PTU inhibited intestinal transit of fluorescent tracers. Finally, thyroxine supplementation restored ENCC mitosis, increased the number of enteric neurons, and recovered intestinal motility in the PTU-treated larvae.<\/jats:p>\n
