GSE99317: Maturing an Enteric Nervous System in Human Intestinal Organoid-derived Tissue-Engineered Small Intestine

  • Organsim human
  • Type RNASEQ
  • Target gene
  • Project ARCHS4

Acquired or congenital disruption in enteric nervous system (ENS) development or function can lead to significant mechanical dysmotility. ENS restoration through cellular transplantation may provide a cure for enteric neuropathies. We have previously generated human pluripotent stem cell (hPSC)-derived tissue-engineered small intestine (TESI) from human intestinal organoids (HIO). However, HIO-TESI fails to develop an ENS. In a previous report of combined HIO with additional human enteric neural crest cells (ENCC), an ENS was established but lacked maturity. The purpose of our study is to establish a mature ENS derived exclusively from hPSC in HIO-TESI. hPSC-derived ENCC supplementation of HIO-TESI generates ENCC-HIO-TESI with mature submucosal and myenteric ganglia, repopulates excitatory, inhibitory, and sensory neurons, and restores the neuroepithelial circuit and neuron-dependent contractility and relaxation. Our findings validate a novel approach to restoring a functional hPSC-derived ENS in ENCC-HIO-TESI and implicate their potential for the treatment of enteric neuropathies.
