Description

VEGF121 is a soluble isoform of VEGF-A that lacks heparin-binding domains. It signals mainly through VEGFR-2 to promote endothelial cell proliferation and migration. VEGF121 is commonly used in vitro to support angiogenesis models and vascularization in organoid and tissue engineering systems.
