Pearson BMP-2 Indirectly Induces Angiogenesis During Large Bone Defect Regeneration 1904 .txt text/plain 350 16 30 To determine whether the angiogenic response to growth factor stimulation was a direct effect of endothelial cell activation or a paracrine effect induced by bone formation, we treated endothelial colony forming cells (ECFCs) with BMP-2, TPO, or hMSC conditioned media and evaluated migration, tubulogenesis, and SMAD 1/5/9 nuclear localization in vitro. These data suggest that the effect of BMP-2 on angiogenesis is secondary to bone formation-induced vascular recruitment rather than direct endothelial cell activation. cache/ng451g08f94.txt txt/ng451g08f94.txt
