Advanced 3D printing for regenerative engineering
Three-dimensional (3D) printing is an emerging tool to fabricate scaffolds for tissue engineering and regenerative medicine, benefited by customized design, tunable internal microstructure, and a wide range applicable material. As a recent technical advancement, 3D printed scaffolds have been incorporated with a controlled delivery of growth factors and/or other bioactive cues to facilitate tissue regeneration, not only providing a temporal structural substrate for cell and tissue ingrowth. This presentation will cover a number of the recent advancements in incorporation of a controlled delivery system in 3D printed scaffolds from hydrogel adsorption and surface coating to chemical integration and embedding microspheres. We will also address the up-to-date research progress for regeneration of complex tissues with various stem/progenitor cells and the 3D printed scaffolds incorporated with controlled delivery systems. In addition, we will discuss the advantages and disadvantages of each delivery method integrated in 3D printed scaffolds, outstanding challenges and future directions.
