Articular cartilage (AC) is a highly specialized tissue which exhibit topographical heterogeneity in terms of matrix composition and mechanical properties. Due to its avascular nature AC shows limited regenerative ability, therefore representing an excellent subject for tissue engineering (TE). Particularly, bioprinting is an emerging additive manufacturing technology that has already demonstrated its potential use in regenerative medicine and cartilage TE. It allows to recapitulate the tissues microstructure by a controlled deposition of “bioinks”, suspensions of cells alone or encapsulated in biomaterials. As cells source, mesenchymal stem cells and chondrocytes, both naturally found in AC, are mainly selected. Hydrogels are largely used as biomaterials for their ability to resemble soft tissues extracellular matrix (ECM), providing an ideal micro-environment for the embedded cells survival, proliferation and differentiation.
