Injured bone-triggered osteokines secretion promotes diabetic wound healing.

ABSTRACT: The treatment of severe diabetic foot remains a clinical challenge. While it is established that bone can exert systemic effects through the secretion of osteokines on other organs, whether this endocrine function can be harnessed to promote diabetic wound healing remains unexplored. Here, we investigate the impact of a bone injury strategy on diabetic wound healing, leveraging the body's innate regenerative capacity to stimulate osteokine release and influence remote skin wound repair. This study demonstrates that the tibial defect significantly accelerates ipsilateral diabetic foot skin wound healing. Mechanistically, we identify osteokines, platelet-derived growth factor-BB (PDGF-BB), as the key to initiating this process. Bone defect triggers a substantial release of PDGF-BB, which rea
