Endothelialized callus organoids drive rapid regeneration of critical-size segmental long bone defects.

Large bone defects remain a major clinical challenge, as current treatments cannot effectively regenerate them and fail to restore functionality. To recapitulate the cellular complexity of the early fracture callus, we engineered human endothelialized callus organoids (hECOs) by co-culturing periosteum-derived skeletal...

Scalable 4D biofabrication process for the manufacture of scaffold-free bone-forming callus implants.

This work establishes a scalable 4D biofabrication process that integrates 3D bioprinting with dissolvable sacrificial alginate bioinks and results in scaffold-free, bone-forming callus implants.
