Three-dimensional Bioprinting for Tissue/Organ Regeneration

Three-dimensional (3D) bioprinting is a group of rapidly growing technology that haspotential applications in tissue engineering and regenerative medicine. This technology allows the precise placement of cells, biomolecules and biomaterials in spatially predefined locations within confined 3D structures, therefore achieving recapitulation of microstructure, architecture, mechanical properties, and biological functions of target tissues and organs. Bioprinting technologies are classified into three main categories, inkjet-based bioprinting, extrusion-based bioprinting and laser-based bioprinting, based on the underlying printing principles. Biomaterial parameters such as biocompatibility, cell viability and the cellular microenvironment strongly influence the bioprinted tissue scaffolds. Various bioprinting technologies and biomaterials have been investigated for printing various types of tissue, including vasculature, heart, bone, cartilage, skin and liver.  In this lecture series, we will discuss basic principles and key aspects of commonly used 3D bioprinting technologies and provide an overview of recent advances in 3D bioprinting technology, as well as design of bioinks suitable for the bioprinting process. We will conclude with current challenges and the future perspectives for further development of 3D organ bioprinting.
