KO Cell Line - VEGF Signaling Pathway KO Cell Line - VEGF Signaling Pathway

The Vascular Endothelial Growth Factor (VEGF) signaling pathway is a key regulator of angiogenesis, controlling endothelial cell growth, migration, and survival. Its dysregulation is closely linked to tumor angiogenesis, cardiovascular, and retinal diseases, making it a critical target for therapeutic research.

VEGF knockout cell lines enable precise pathway studies and disease modeling. Below, explore EDITGENE's validated VEGF pathway KO cell models and their key research applications.

The VEGF signaling pathway (Vascular Endothelial Growth Factor signaling pathway) is a central regulatory mechanism of angiogenesis, playing critical roles in both physiological and pathological processes.

Through activation of VEGF ligands and receptors, this pathway regulates the proliferation, migration, and survival of endothelial cells (ECs), enabling the controlled formation of new blood vessels during development, tissue repair, and regeneration.

However, dysregulation of VEGF signaling can lead to disease. Excessive VEGF activity promotes tumor growth, invasion, and metastasis by stimulating abnormal angiogenesis, whereas insufficient signaling can impair wound healing and contribute to ischemic disorders.

Because of its essential role in vascular biology and disease progression, the VEGF signaling pathway has become a major therapeutic target. A deeper understanding of VEGF pathway regulation is therefore critical for the development of anti-angiogenic therapies and novel disease treatments.

VEGF ligands and their receptors play diverse roles in multiple pathological processes, including tumor angiogenesis, cardiovascular diseases, ocular disorders, and metabolic, immune, and reproductive diseases. Dysregulation of key molecular interactions and downstream signaling pathways can enhance cell survival, migration, and proliferation, contributing to diseases such as: Atherosclerosis (ATH), Myocardial infarction (MI), Diabetic retinopathy (DR), Age-related macular degeneration (AMD), Non-alcoholic fatty liver disease (NAFLD), Rheumatoid arthritis (RA), Preeclampsia (PE), Endometriosis (EM)

These disease contexts highlight the strong therapeutic potential of targeting the VEGF signaling pathway.

Gene knockout cell models provide powerful tools to investigate the regulatory functions of VEGF family members in different disease settings, supporting mechanistic studies, target validation, and drug discovery.
