Three-dimensional (3D) bioprinting technologies have been developed to offer construction of biological tissue constructs that mimic the anatomical and functional features of native tissues or organs. These cutting-edge technologies could make it possible to precisely place multiple cell types and biomaterials in a single 3D tissue construct. Hence, 3D bioprinting is one of the most attractive and powerful tools to provide more anatomical and functional similarity of human tissues or organs in tissue engineering and regenerative medicine. In recent years, this 3D bioprinting continually shows promise for building complex soft tissue constructs through placement of cell-laden hydrogel-based bioinks in a layer-by-layer fashion. This review will discuss bioprinting technologies and their applications in soft tissue regeneration.
