Abstract (original English)
Three-dimensional (3D) extrusion-based bioprinting is the most widely used bioprinting technology to fabricate bionic tissue or organ constructs by combining biomaterial ink and living cells for tissue engineering and regenerative medicine. One critical issue of this technique is the selection of suitable biomaterial ink to simulate extracellular matrix (ECM) that provides mechanical support for cells and regulates their physiological activities. Previous studies have demonstrated that it is an enormous challenge to form and maintain reproducible 3D constructs and eventually achieve the balance among biocompatibility, mechanical properties, and printability. This review highlights the properties of extrusion-based biomaterial inks and recent developments as well as details various biomaterial inks classified by their function. Key approaches related to their modification methods according to the functional requirements are also discussed, along with the selection strategies by varying extrusion paths and methods in extrusion-based bioprinting. This systematical review will assist researchers in identifying the most suitable extrusion-based biomaterial inks based on their requirements, as well as in elaborating current challenges and prospects of extrudable biomaterial inks in the field of bioprinting of in vitro tissue models.
