Co-Treatment With rhBMP-2 and Rapamycin Modulates Osteogenesis-Adipogenesis Balance to Enhance Aged Bone Regeneration. [PDF]

Adv Sci (Weinh)
This study demonstrates that the imbalance between osteogenic and adipogenic differentiation in senescent BMSCs, leading to excessive adipocyte accumulation, which subsequently impairs bone regeneration in aged mice. To address this pathological dysregulation, a novel energy‐supplying hydrogel system (PBR) has been developed to restore balanced ...
