PGF

PGF is a growth factor found in placenta which is homologous to vascular endothelial growth factor.

Full Name

Placental Growth Factor

Function

Growth factor active in angiogenesis and endothelial cell growth, stimulating their proliferation and migration. It binds to the receptor FLT1/VEGFR-1. Isoform PlGF-2 binds NRP1/neuropilin-1 and NRP2/neuropilin-2 in a heparin-dependent manner. Also promotes cell tumor growth.

Cellular Location

Secreted
The three isoforms are secreted but PlGF-2 appears to remain cell attached unless released by heparin.
