Abstract Type II collagen (CII), a key component of cartilaginous tissues, offers an attractive option for fabricating biomimetic scaffolds that provide mechanical support and biochemical signals to facilitate cell adhesion, proliferation, and differentiation. Advances in fabrication technologies have enabled the creation of intricate and multicellular CII-based scaffolds that more accurately replicate the natural structure of tissues. Here, we review the application of CII in tissue engineering and highlight its crucial contributions to the regeneration of hyaline cartilage and intervertebral discs. Additionally, we discuss the versatile roles of CII in other biomedical applications, including disease modeling, bone regeneration, and the development of artificial immune organs.
