Organoid bioprinting strategy and application in biomedicine: A review

Organoids are three-dimensional cell structures cultured in vitro. They are self-organizing and can mimic real organs in structure and function. Bioprinting technology breaks through some limitations of organoid manufacturing, making it more widely used in drug screening, regenerative medicine, and other fields. In this review, we first introduce bioinks and bioprinting methods for stem cell and organoid bioprinting, then summarize several vascularization strategies for bioprinting organoids, and present applications in biomedicine. In the future, the development of microfluidic technology and four-dimensional bioprinting technology may be conducive to forming better bioprinted organoids.
