SLIT3/ROBO1 axis contributes to angiogenic–osteogenic coupling in endothelial progenitor cells and peripheral blood mesenchymal stem cells

Key Points

• This research aims to investigate how the SLIT3/ROBO1 axis influences the coupling of angiogenesis and osteogenesis in specific stem cells.
• Examined the interaction between SLIT3 and ROBO1 in endothelial progenitor cells and peripheral blood mesenchymal stem cells.
• Analyzed the effects of EPCs and PBMSCs sheets on vascularization and osteogenesis.
• Utilized in vitro and in vivo models to assess angiogenic and osteogenic responses.
• Found that the SLIT3/ROBO1 axis significantly improves the coupling between angiogenesis and osteogenesis.
• EPCs and PBMSCs sheets were shown to enhance vascularization, addressing earlier limitations in vascular growth.
• Demonstrated augmented osteogenic effects due to this coupling mechanism.
