Abstract:
Three-dimensional bioprinting technology has shown excellent application prospect in recent years in the field of tissue engineering and regenerative medicine due to its ability to fabricate tissue-engineered grafts with delicate structures through programmed control. Here we briefly describe the basic steps of bioprinting, discuss the recent applications of bioprinting in tissue engineering and analyze the general strategies for bioprinting functional tissue constructs. We review three types of bioprinting approaches (sacrificial bioprinting, hydrogel-embedded bioprinting, gradient bioprinting) with a focus on nozzle-based techniques and respective advantages of extrusion bioprinters, and finally summarize the limitations of current technologies and provide an outlook on their future development.
