General description

VEGF121 is expressed in human HEK 293 cells as a disulfide linked, glycosylated cytokine with an apparent molecular mass of 37 kDa as a homodimer and 50 kDa as a homotrimer. Production in human HEK 293 cells offers authentic glycosylation. Glycosylation contributes to stability in cell growth media and other applications.

Biochem/physiol Actions

VEGF121 belongs to the PDGF/VEGF growth factor family characterized by the presence of eight conserved cysteine residues and a cystine knot structure. VEGF is secreted by the majority of tumor cells and initiates angiogenesis by activating endothelial cells of existing blood vessels and promoting their migration.
VEGF has also been implicated in correlation with poor prognosis in breast cancer.
In addition, VEGF is released in rheumatoid arthritis in response to TNF-α, increasing endothelial permeability and stimulating angiogenesis (formation of capillaries).

Analysis Note

The specific activity was determined by the dose-dependent stimulation of the proliferation of HUVEC cells (human umbilical vein endothelial cells).

Vascular endothelial growth factor (VEGF) is a secreted mitogen highly specific for cultured endothelial cells. In vivo VEGF induces microvascular permeability and plays a central role in both angiogenesis and vasculogenesis. VEGF is a promising target for therapeutic intervention in

Breast cancer development largely depends upon the essential contributions from the tumor microenvironment, where several inflammatory cell populations (e.g. macrophages) orchestrate breast cancer development. The majority of tumor-associated macrophages (TAMs) exhibit alternatively activated M2 properties, produce abundant anti-inflammatory factors and
