Fatty acid binding protein 4 induces osteogenesis and angiogenesis as pathogenesis of metabolic osteoarthritis.

ABSTRACT:

Background

The pathogenesis of osteoarthritis (OA) is not yet fully elucidated. FABP4 plays a role in the occurrence of metabolic OA, however, the mechanism remains unclear. The purpose of this study was to further explore the mechanism by which FABP4 mediates the occurrence of metabolic OA.

Methods

In vivo, FABP4 knockout mice (KO) and wild-type littermates (WT) were fed with high-fat diet (HFD) for 3 and 6 months. WT mice were fed with HFD and treated with FABP4 inhibitor BMS309403 (30 mg/kg/d) or vehicle for 6 months. Knee cartilage degenerative changes and subchondral bone changes were assessed. In vitro, FABP4 was used to stimulate mouse bone marrow mesenchymal stem cells (mMSCs) and endothelial progenitor cells (EPCs). Osteogenesis and angiogenesis were assessed.
