Here we report an integrated strategy to engineer a 2.5-cm esophageal segment by microinjecting autologous pericyte-like myogenic precursors and fibroblasts in a decellularized porcine scaffold to repair circumferential defects in 10-kg minipigs (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u20098), modeling pediatric use. Bioreactor maturation induced a proangiogenic phenotype, with in vivo support from biodegradable intraluminal stents and a vascularizing pleural wrap. This coordinated approach yielded safe and effective esophageal conduits; oral feeding supported normal growth, morbidity resembled that of clinical esophageal replacement and was endoscopically manageable, and 63% (5\/8) survived to the 6-month endpoint. Comprehensive multimodal analyses demonstrated progressive recapitulation of native architecture, with increasing neuromuscular regeneration and vascularization, correlating with functional recovery, absence of symptomatic stricture and the presence of secondary peristalsis by 6\u2009months. These results demonstrate that the combination of complementary regenerative, conditioning and surgical strategies enables a functionally integrated, contractile esophageal graft with ongoing structural maturation without immunosuppression.\n                  <\/jats:p>","DOI":"10.1038\/s41587-026-03043-1","type":"journal-article","created":{"date-parts":[[2026,3,20]],"date-time":"2026-03-20T10:01:27Z","timestamp":1774000887000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Functional integration of an autologous engineered esophagus in a large-animal model"],"prefix":"10.1038","author":[{"given":"Natalie","family":"Durkin","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4828-0668","authenticated-orcid":false,"given":"George T.","family":"Hall","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roberto","family":"Lutman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marianna","family":"Scuglia","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3682-8873","authenticated-orcid":false,"given":"Theodoros","family":"Xenakis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giulia","family":"Patera","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniele","family":"Di Biagio","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-9701-3018","authenticated-orcid":false,"given":"Koji","family":"Yamada","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lucinda","family":"Tullie","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0441-2198","authenticated-orcid":false,"given":"Dominic","family":"Scaglioni","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4274-1312","authenticated-orcid":false,"given":"Soichi","family":"Shibuya","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8968-8926","authenticated-orcid":false,"given":"Kornilia","family":"Nikaki","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Max Arran","family":"Beesley","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tarek","family":"Saleh","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matias","family":"Garrido Flores","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4880-8047","authenticated-orcid":false,"given":"Dominika","family":"Borselle","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Valerija","family":"Karaluka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1708-2634","authenticated-orcid":false,"given":"J.
