In 2013, Mustata et al. described the isolation of intestinal fetal progenitors growing as spheroids in the ex vivo culture system initially implemented by Sato et al. (2009) to grow adult intestinal stem cells. Noteworthy, fetal-derived spheroids have high self-renewal capacity making easy their indefinite maintenance in culture. Here, we report an adapted protocol for isolation and ex vivo culture and maintenance of fetal epithelial progenitors from distal pre-glandular stomach growing as gastric spheroids (Fernandez Vallone et al., 2016).
