Dio-labeled hUSCs were seeded onto porcine urethral decellularized matrices and grouped by exosome concentration (0, 50, 100\u202f\u03bcg\/mL). Cell proliferation and distribution were examined under a fluorescence inverted microscope on days 1, 3, and 7. On day 7, samples were paraffin-embedded for histological analysis of cell integration. hUSCs with mesenchymal stem cell (MSC) properties were successfully isolated, and exosomes extracted via centrifugation. hUSCs-exosome (Exo) enhanced cell migration but did not significantly affect proliferation. Dio-labeling and H&amp;E staining confirmed hUSC presence and attachment to the urethral matrix, while CD44 immunohistochemistry confirmed the presence and attachment of hUSCs within the scaffold. Exosomes derived from hUSCs did not significantly enhance cell proliferation in the construction of the porcine urethral decellularized matrix-hUSC complex. The specific exosomal cargo responsible for these differential effects on migration versus proliferation was not examined in this study and will be the focus of future investigations.\n                  <\/jats:p>","DOI":"10.1515\/biol-2025-1320","type":"journal-article","created":{"date-parts":[[2026,5,3]],"date-time":"2026-05-03T03:11:31Z","timestamp":1777777891000},"source":"Crossref","is-referenced-by-count":0,"title":["Exosomes from human urine-derived stem cells in porcine urethral scaffold construction"],"prefix":"10.1515","volume":"21","author":[{"given":"Kai-Yue","family":"Zhang","sequence":"first","affiliation":[{"name":"Department of Urology , Inner Mongolia Baogang Hospital , Baotou , 014010 , China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hao","family":"Zhong","sequence":"additional","affiliation":[{"name":"Department of Urology , Inner Mongolia Baogang Hospital , Baotou , 014010 , China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei-De","family":"Ma","sequence":"additional","affiliation":[{"name":"Department of Urology , Inner Mongolia Baogang Hospital , Baotou , 014010 , China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiao-Yan","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Urology , Inner Mongolia Baogang Hospital , Baotou , 014010 , China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Li-Zhong","family":"Han","sequence":"additional","affiliation":[{"name":"Department of Urology , Inner Mongolia Baogang Hospital , Baotou , 014010 , China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhi-Zhong","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Urology , Inner Mongolia Baogang Hospital , Baotou , 014010 , China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"374","published-online":{"date-parts":[[2026,5,4]]},"reference":[{"key":"2026050303112688716_j_biol-2025-1320_ref_001","doi-asserted-by":"crossref","unstructured":"Wessells, H, Morey, A, Souter, L, Rahimi, L, Vanni, A.
