3D bioprinting of multilayered scaffolds with spatially differentiated ADMSCs for rotator cuff tendon-to-bone interface regeneration

Applied Materials Today 2022 Volume 27, Article 101510

Regeneration of the gradient structure of the tendon-to-bone interface is still a significant clinical challenge. This study reports a novel therapeutic method combining three-dimensional (3D) bioprinting and melt electrospinning writing techniques to regenerate a functional tendon-to-bone interface. We generated biomimetic multilayered scaffolds with 3D-bioprinted pre-differentiated autologous adipose-derived mesenchymal stem cells (ADMSC), which recapitulated compositional and cellular structures of the interface. The hydrogel-based bioinks offered high cell viability and proliferative capability for rabbit ADMSCs. The hydrogels with pre-differentiated (into tenogenic, chondrogenic, and osteogenic lineages) or undifferentiated rabbit ADMSCs were 3D-bioprinted into zonal-specific constructs to mimic the structure of the tendon-to-bone interface.…
