Three isoforms of platelet-derived growth factors all have the capability to induce angiogenesis in vivo

Biol Pharm Bull. 1994 Dec;17(12):1686-8. doi: 10.1248/bpb.17.1686.


Three isoforms of platelet-derived growth factors (PDGFs) composing of AA, AB, and BB chains all exhibited angiogenic activity in a dose-dependent manner in an in vivo assay system involving the chorioallantoic membrane of chick embryo. The order of potency as BB > AB = AA. They, however, failed to stimulate proliferation of vascular endothelial cells, suggesting that their effects are indirect. These data suggest that possibility that three PDGF isoforms are indirect angiogenic factors.
