The objective of this study was to generate jejunum and colon organoids from suckling and weaned piglets in order to determine the extent to which organoids retain a location-specific and a developmental stage-specific phenotype. Organoids were studied at three time points by gene expression profiling for comparison with the transcriptomic patterns observed in crypts <jats:italic>in vivo<\/jats:italic>. In addition, the gut microbiota and the metabolome were analyzed to characterize the luminal environment of epithelial cells at the origin of organoids. The location-specific expression of 60 genes differentially expressed between jejunum and colon crypts from suckling piglets was partially retained (48%) in the derived organoids at all time point. The regional expression of these genes was independent of luminal signals since the major differences in microbiota and metabolome observed <jats:italic>in vivo<\/jats:italic> between the jejunum and the colon were not reproduced <jats:italic>in vitro<\/jats:italic>. In contrast, the regional expression of other genes was erased in organoids. Moreover, the developmental stage-specific expression of 30 genes differentially expressed between the jejunum crypts of suckling and weaned piglets was not stably retained in the derived organoids. Differentiation of organoids was necessary to observe the regional expression of certain genes while it was not sufficient to reproduce developmental stage-specific expression patterns. In conclusion, piglet intestinal organoids retained a location-specific phenotype while the characteristics of developmental stage were erased <jats:italic>in vitro<\/jats:italic>. Reproducing more closely the luminal environment might help to increase the physiological relevance of intestinal organoids.<\/jats:p>","DOI":"10.3389\/fcell.2022.983031","type":"journal-article","created":{"date-parts":[[2022,8,29]],"date-time":"2022-08-29T08:51:39Z","timestamp":1661763099000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":19,"title":["The phenotype of the gut region is more stably retained than developmental stage in piglet intestinal organoids"],"prefix":"10.3389","volume":"10","author":[{"given":"Elo\u00efse","family":"Mussard","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Corinne","family":"Lencina","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lise","family":"Gallo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C\u00e9line","family":"Barilly","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maryse","family":"Poli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katia","family":"Feve","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mikael","family":"Albin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laurent","family":"Cauquil","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christelle","family":"Knudsen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caroline","family":"Achard","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guillaume","family":"Devailly","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laura","family":"Soler","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sylvie","family":"Combes","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"Beaumont","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2022,8,29]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"69","DOI":"10.1186\/1471-2164-6-69","article-title":"Changes in the transcriptional profile of transporters in the intestine along the anterior-posterior and crypt-villus axes","volume":"6","author":"Anderle","year":"2005","journal-title":"BMC Genomics"},{"key":"B2","doi-asserted-by":"publisher","first-page":"1430","DOI":"10.1096\/fj.201902514R","article-title":"Post\u2010natal co\u2010development of the microbiota and gut barrier function follows different paths in the small and large intestine in piglets","volume":"34","author":"Arnaud","year":"2020","journal-title":"FASEB J."},{"key":"B3","doi-asserted-by":"publisher","first-page":"19","DOI":"10.1038\/nrm3721","article-title":"Adult intestinal stem cells: Critical drivers of epithelial homeostasis and regeneration","volume":"15","author":"Barker","year":"2014","journal-title":"Nat.
