Chondrocyte spheroid-laden microporous hydrogel-based 3D bioprinting for cartilage regeneration
Three-dimensional (3D) bioprinting has brought new promising strategies for the regeneration of cartilage with specific shapes. In cartilage bioprinting, chondrocyte-laden hydrogels are the most commonly used bioinks. However, the dispersion of cells and the dense texture of the hydrogel in the conventional bioink may limit cell–cell/ cell–extracellular matrix (ECM) interactions, counting against cartilage regeneration and maturation. To address this issue, in this study, we developed a functional bioink for cartilage bioprinting based on chondrocyte spheroids (CSs) and microporous hydrogels, in which CSs as multicellular aggregates can provide extensive cell– cell/cell–ECM interactions to mimic the natural cartilage microenvironment, and microporous hydrogels…
