3D Bioprinting for Tissue Regeneration: Various Bioink Strategies

3D bioprinting is an emerging area of current interest to scientists. This rapid prototyping technology allowed the fabrication of 3D scaffolds with precise architecture and controlled delivery of cell-laden bioink. The reason for the increasing popularity of 3D bioprinting is its high potential to construct tissues, organs, and other biological systems in vitro that mimic their native counterparts. The advocated 3D bioprinting technique enables the construction of tissue-engineered 3D artificial bone by layer-by-layer deposition of osteogenic cells and bone-specific growth supplements at a particular spatial arrangement. Mainly 3D bioprinting process uses hydrogel materials since it can encapsulate the cells inside the polymer network to provide a supportive environment and protects from external damage.
