Abstract (original English)
Osteoporosis invariably manifests as loss of bone, which is replaced by adipose tissue; this can easily lead to fractures, accompanied by delayed and poor healing. Adiponectin (APN) balances osteogenesis and adipogenesis in bone marrow mesenchymal stem cells (BMSCs). Therefore, this study explored whether adiponectin promotes bone fracture healing by regulating the balance between osteogenesis and adipogenesis. We used adenovirus overexpression vectors carrying APN (Ad-APN-GFP) to treat ovariectomized (OVX) mouse BMSCs and osteoporotic bone fractures to investigate the role of APN in bone microenvironment metabolism in osteoporotic fractures. We subsequently established an OVX mice and bone fracture model using Ad-APN-GFP treatment to investigate whether APN could promote bone fracture healing in osteoporotic mice. The experimental results showed that APN is a critical molecule in diverse differentiation directions in OVX mouse BMSCs, with pro-osteogenesis and anti-adipogenesis properties. Importantly, our study revealed that Ad-APN-GFP treatment facilitates bone generation and healing around the osteoporotic fracture ends. Moreover, we identified that Sirt1 and Wnt signaling were closely related to the pro-osteogenesis and anti-adipogenesis commitment of APN in OVX mouse BMSCs and femoral tissues. We demonstrated that APN overexpression facilitates bone fracture healing in ost
