However, attack from the host immune system represents a major challenge, requiring chronic immunosuppression to enable long-lived cell transplantation <i>in vivo</i>. Encapsulating cells in engineered biomaterials capable of excluding components of the host immune system while allowing for the transport of therapeutic proteins, oxygen, nutrients, metabolites, and waste products represents a potential solution. However, the foreign-body response can lead to isolation from native vasculature and hypoxia leading to cell death. In this prospective article, we highlight materials-based solutions to three important challenges in the field: (i) improving biocompatibility and reducing fibrosis; (ii) enhancing transport of secreted protein drugs and key nutrients and oxygen <i>via</i> engineered, semipermeable membranes; and (iii) improving oxygenation. These efforts draw on several disciplines in materials' research, including polymer science, surfaces, membranes, biomaterials' microfabrication, and flexible electronics. If successful, these efforts could lead to new therapies for chronic disease and are a rich space for both fundamental materials' discovery and applied translational science.</p><p><strong>Graphical abstract: </strong></p>","PeriodicalId":19016,"journal":{"name":"MRS Communications","volume":"15 1","pages":"21-33"},"PeriodicalIF":1.8,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11825545/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143433540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
