主 题:3D bioprinting Hydrogel bioink Biomaterial High resolution and fidelity
摘 要:Recently,3D bioprinting has been explored as a promising technology for biomedical applications with the potential to create complex structures with precise *** encapsulated hydrogels composed of materials such as gelatin,collagen,hyaluronic acid,alginate and polyethylene glycol have been widely used as bioinks for 3D ***,since most hydrogel-based bioinks may not allow rapid stabilization immediately after 3D bioprinting,achieving high resolution and fidelity to the intended architecture is a common challenge in 3D bioprinting of *** this study,we have utilized shear-thinning and self-healing ionically crosslinked oxidized and methacrylated alginates(OMAs)as a bioink,which can be rapidly gelled by its self-healing property after bioprinting and further stabilized via secondary *** was successfully demonstrated that stem cell-laden calcium-crosslinked OMA hydrogels can be bioprinted into complicated 3D tissue structures with both high resolution and *** photocrosslinking enables long-term culture of 3D bioprinted constructs for formation of functional tissue by differentiation of encapsulated human mesenchymal stem cells.
