To enhance the tendon-bone healing potential of SIS, we modified it with extracellular matrix (ECM) derived from bone marrow\u2212derived mesenchymal stem cells (BM-MSCs), generating a scaffold termed BME-SIS. The morphology, surface roughness, hydrophilicity, mechanical properties, and growth factor content of BME-SIS were systematically characterized. In vitro, the BME-SIS extract significantly promoted BM-MSC proliferation, migration, and the expression of osteogenic, chondrogenic, and tenogenic lineage-related differentiation markers, despite its slightly reduced mechanical strength. In a rat model of RCT, BME-SIS was implanted at the tendon-bone interface (TBI) and evaluated at four and eight weeks post surgery by gait analysis, biomechanical testing, microcomputed tomography, magnetic resonance imaging, and histological assessment. Compared with SIS, BME-SIS exhibited increased surface roughness, enhanced hydrophilicity, and enriched growth factors, which translated into superior biological performance. In vivo, BME-SIS markedly improved gait recovery, facilitated tendon-bone integration, and promoted cartilage regeneration at the TBI. Collectively, these results demonstrate that BM-MSC-derived ECM significantly augments the reparative potential of SIS, highlighting BME-SIS as a promising biomaterial for RCT repair.<\/jats:p>","DOI":"10.1021\/acsami.6c07394","type":"journal-article","created":{"date-parts":[[2026,8,14]],"date-time":"2026-08-14T05:02:09Z","timestamp":1786683729000},"page":"44905-44918","source":"Crossref","is-referenced-by-count":0,"title":["Stem Cell-Derived Extracellular Matrix Biofunctionalized Small Intestinal Submucosa for the Repair of Rotator Cuff Tears"],"prefix":"10.1021","volume":"18","author":[{"given":"Yao","family":"Tong","sequence":"first","affiliation":[{"name":"West China Hospital, Sichuan University , , ,","place":["Chengdu, China, 610041"]},{"name":"West China Hospital, Sichuan University , , ,","place":["Chengdu, China, 610041"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chunsen","family":"Zhang","sequence":"additional","affiliation":[{"name":"West China Hospital, Sichuan University , , ,","place":["Chengdu, China, 610041"]},{"name":"West China Hospital, Sichuan University , , ,","place":["Chengdu, China, 610041"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Songyun","family":"Yang","sequence":"additional","affiliation":[{"name":"West China Hospital, Sichuan University , , ,","place":["Chengdu, China, 610041"]},{"name":"West China Hospital, Sichuan University , , ,","place":["Chengdu, China, 610041"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongfu","family":"Jin","sequence":"additional","affiliation":[{"name":"West China Hospital, Sichuan University , , ,","place":["Chengdu, China, 610041"]},{"name":"West China Hospital, Sichuan University , , ,","place":["Chengdu, China, 610041"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guoxu","family":"Zhang","sequence":"additional","affiliation":[{"name":"West China Hospital, Sichuan University , , ,","place":["Chengdu, China, 610041"]},{"name":"West China Hospital, Sichuan University , , ,","place":["Chengdu, China, 610041"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sijie","family":"Chen","sequence":"additional","affiliation":[{"name":"West China Hospital, Sichuan University , , ,","place":["Chengdu, China, 610041"]},{"name":"West China Hospital, Sichuan University , , ,","place":["Chengdu, China, 610041"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiahui","family":"Chen","sequence":"additional","affiliation":[{"name":"West China Hospital, Sichuan University , , ,","place":["Chengdu, China, 610041"]},{"name":"West China Hospital, Sichuan University , , ,","place":["Chengdu, China, 610041"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin","family":"Tang","sequence":"additional","affiliation":[{"name":"West China Hospital, Sichuan University , , ,","place":["Chengdu, China, 610041"]},{"name":"West China Hospital, Sichuan University , , ,","place":["Chengdu, China, 610041"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1940-3814","authenticated-orcid":true,"given":"Yizhou","family":"Huang","sequence":"additional","affiliation":[{"name":"West China Hospital, Sichuan University , , ,","place":["Chengdu, China, 610041"]},{"name":"West China Hospital, Sichuan University , , ,","place":["Chengdu, China, 610041"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,8,14]]},"reference":[{"issue":"1","key":"2026091814064048000_cit1","doi-asserted-by":"publisher","first-page":"116","DOI":"10.1016\/j.jse.2009.04.006","article-title":"Prevalence and risk factors of a rotator cuff tear in the general population","volume":"19","author":"Yamamoto","year":"2010","journal-title":"J.
