Vascular endothelial growth factor (VEGF-A) is a crucial stimulator of vascular cell migration
and proliferation. Using bone marrow–derived human adult mesenchymal stem cells
(MSCs) that did not express VEGF receptors, we provide evidence that VEGF-A can
stimulate platelet-derived growth factor receptors (PDGFRs), thereby regulating MSC
migration and proliferation. VEGF-A binds to both PDGFRα and PDGFRβ and induces

Vascular endothelial growth factor (VEGF-A) is a crucial stimulator of vascular cell migration and proliferation. Using bone marrow–derived human adult mesenchymal stem cells (MSCs) that did not express VEGF receptors, we provide evidence that VEGF-A can stimulate platelet-derived growth factor receptors (PDGFRs), thereby regulating MSC migration and proliferation. VEGF-A binds to both PDGFRα and PDGFRβ and induces tyrosine phosphorylation that, when inhibited, results in attenuation of VEGF-A–induced MSC migration and proliferation. This mechanism was also shown to mediate human dermal fibroblast (HDF) migration. VEGF-A/PDGFR signaling has the potential to regulate vascular cell recruitment and proliferation during tissue regeneration and disease.
