VEGF signaling through VEGF receptors guides endothelial proliferation, migration, and vessel patterning—core themes in angiogenesis research.
What it is
Angiogenesis is the formation of new capillary structures from existing vessels. VEGF-A and related ligands acting on VEGFR-1/2 are central molecular players in textbooks and research pipelines.
How it works
VEGF binding activates receptor tyrosine kinases on endothelial cells, engaging PLCγ, PI3K/AKT, and MAPK branches that support survival, motility, and tube formation phenotypes in experimental assays.
Tissue remodeling pages often cross-link here because matrix turnover and vessel growth are coordinated in many injury models.
Biological role
Physiological angiogenesis supports development, wound repair, and menstrual cycling; pathological angiogenesis appears in tumor and retinal disease literature. Educational peptide pages should specify which context a citation uses.
Proteins involved
- VEGF-A
- VEGFR-2 (KDR/Flk-1)
- Neuropilins
- PI3K/AKT and MAPK modules
Research summary
Foundational vascular biology defines VEGF receptor cascades. Peptide papers that mention angiogenesis usually report proxy markers; those markers are not interchangeable with functional perfusion outcomes.
Descriptions summarize published mechanistic frameworks. Findings from cell culture or animal models should not be interpreted as proven clinical effects in humans.
