Abstract
3D bioprinting is one of the advanced biomedical applications of the 3D printing technology, and the bioink is the most important component of 3D bioprinting process. Different bioinks are developed based on printer types. Development of tailor-made bioinks for different tissue engineering applications and developing universal bioinks with the capacity to carry different growth factors for different tissues are the two focus areas of the current research in bioink. In this chapter, uses of various forms of cellulose [modified cellulose, nanofibrillated cellulose (NFC), cellulose nanocrystals (CNCs)] in the development of various cell-laden bioinks are discussed in the context of 3D printing.
