Vasculargrowthrelated

Vasculargrowthrelated is a broad term used to describe the set of biological processes, mediators, and research focused on the growth and remodeling of the vascular system, including blood and lymphatic vessels. It encompasses angiogenesis (formation of new vessels from existing ones), vasculogenesis (de novo vessel formation from progenitor cells), arteriogenesis (maturation and enlargement of arteries), and lymphangiogenesis (growth of lymphatic vessels). These processes are essential during embryonic development and tissue repair, but can contribute to disease when dysregulated, such as in cancer, diabetic retinopathy, age-related macular degeneration, and ischemic conditions.

Molecular regulation is complex, with hypoxia-driven signaling playing a central role. Hypoxia-inducible factors induce pro-angiogenic factors, notably vascular endothelial growth factor (VEGF). Other growth factors include fibroblast growth factor (FGF), platelet-derived growth factor (PDGF), and angiopoietins. Receptors such as VEGFR, FGFR, and Tie2 mediate signaling cascades (PI3K/Akt, MAPK) that promote endothelial proliferation and vessel formation. Notch, Wnt, and TGF-beta pathways provide context-dependent regulatory inputs, guiding sprouting, branching, and maturation. Extracellular matrix remodeling by matrix metalloproteinases and pericyte or smooth muscle cell recruitment are important for vessel stabilization.

In research and medicine, vasculargrowthrelated studies use in vitro assays of endothelial tube formation, sprouting assays, and in vivo models (mouse retina, zebrafish) to study vessel growth. Clinically, anti-angiogenic therapies targeting VEGF signaling are used to treat cancer and ocular neovascular diseases, while strategies to promote vascular growth are explored for tissue engineering and ischemic tissue repair. Understanding the balance of pro- and anti-angiogenic signals underpins approaches to modulate vascular growth in different contexts.
