The review article summarizes the applications of photopolymerized hydrogels in tissue engineering. In this article, we discussed the types and advantages of different photoinitiators, as well as the advantages of manufacturing technologies for photopolymerized hydrogels and the materials used in tissue engineering. [Display omitted] Owing to the special formation of photopolymerized hydrogels, they can effectively control the formation of hydrogels in space and time. Moreover, the photopolymerized hydrogels have mild formation conditions and biocompatibility; therefore, they can be widely used in tissue engineering. With the development and application of manufacturing technology, photopolymerized hydrogels can be widely used in cell encapsulation, scaffold materials, and other tissue engineering fields through more elaborate manufacturing methods. This review covers the types of photoinitiators, manufacturing technologies for photopolymerized hydrogels as well as the materials used, and a summary of the applications of photopolymerized hydrogels in tissue engineering.
