1654-Organoids for Rapid Long Bone Regeneration
This research introduces human endothelialized callus organoids (hECOs) as a novel method for repairing large, non-healing bone injuries. By combining periosteum-derived skeletal progenitors with endothelial cells, the authors successfully mimicked the complex cellular environment of a natural fracture callus. These organoids demonstrated accelerated chondrogenic differentiation and enhanced extracellular matrix maturation through critical molecular signaling between cell types. When fused into macroscale aggregates and implanted into mice, the constructs facilitated rapid host…
