Abstract
Localized gene delivery via engineered scaffolds offers spatiotemporal control of the gene vector release. Here, we explored the capability of digital light processing based bioprinting to fabricate 3D scaffolds in hydrogels for controlled gene delivery. We demonstrated the compatibility of the method with three representative hydrogel biomaterials for gene delivery. We further investigated the highly tunable release profile with these scaffolds by creating and combining distinct release mechanisms of diffusion and ion exchange. The efficacy of gene delivery of these scaffolds was validated in vitro using 293T cells. Results from this work could potentially facilitate the development of synergistic and personalized gene therapies.
期刊介绍：
Bioprinting is a broad-spectrum, multidisciplinary journal that covers all aspects of 3D fabrication technology involving biological tissues, organs and cells for medical and biotechnology applications. Topics covered include nanomaterials, biomaterials, scaffolds, 3D printing technology, imaging and CAD/CAM software and hardware, post-printing bioreactor maturation, cell and biological factor patterning, biofabrication, tissue engineering and other applications of 3D bioprinting technology. Bioprinting publishes research reports describing novel results with high clinical significance in all areas of 3D bioprinting research. Bioprinting issues contain a wide variety of review and analysis articles covering topics relevant to 3D bioprinting ranging from basic biological, material and technical advances to pre-clinical and clinical applications of 3D bioprinting.
