scRNA-seq of human fetal duodenal enteroids grown in EGF and/or NRG1. scRNA-seq of human fetal duodenal enteroids grown in EGF and/or NRG1

The purpose of this study was to interrogate the role of EGF-family ligands, in particular Epidermal Growth Factor (EGF) and Neuregulin 1 (NRG1), as human intestinal stem cell niche factors. An established duodenal enteroid line derived from a 20.2 week post conception biological specimen was exposed to either EGF or NRG1 for five days, after which scRNA-seq was performed to assess changes in gene expression and cellular composition. In an independent experiment, scRNA-seq was performed on freshly isolated duodenal epithelium from a 15 week specimen cultured in the presence of EGF, NRG1, or both EGF and NRG1 after 2 passages.
