Despite notable progress in surgical techniques, these methods continue to grapple with hurdles such as complications and suboptimal healing effects. In this study, we prepared a three‐dimensional‐printed composite scaffold by incorporating bioactive ceramic zinc silicate (Zn2SiO4) into sodium alginate (SA) hydrogel. The physicochemical properties and mechanical strength of the SA hydrogel scaffold composited with Zn2SiO4 (ZnSi/SA) were investigated in vitro. Impressively, the 0.5‐ZnSi/SA scaffold exhibited a sustained release of Zn and Si ions, while exhibiting mechanical properties compatible with tendon–bone interface repair. Moreover, cell viability, cell migration, and osteogenic differentiation assay results showed that 0.5‐ZnSi/SA scaffold facilitated the viability, mobility, and osteogenic differentiation of bone marrow stromal cells. In parallel, assessments of cell viability, cell migration, and tendon differentiation indicated that 0.5‐ZnSi/SA scaffold promoted the viability, migration, and tenogenic differentiation of tendon stem/progenitor cells. Moreover, cell viability, cell migration, and tube formation assay results demonstrated that 0.5‐ZnSi/SA scaffold enhanced the viability, migration rate, and angiogenic performance of human umbilical vein endothelial cells. Collectively, our findings suggest a promising therapeutic avenue employing ZnSi/SA scaffold for tendon–bone interface healing.","PeriodicalId":100901,"journal":{"name":"MedComm – Biomaterials and Applications","volume":"2 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mba2.61","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50136685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
