Angiogenesis promotion refers to the physiological process of stimulating the formation of new blood vessels from pre-existing vasculature. This vital biological event is essential for tissue repair, wound healing, and growth throughout the human body. In the context of hormonal health and longevity, controlled promotion can support better tissue perfusion and nutrient delivery. However, uncontrolled or pathological angiogenesis is a hallmark of certain disease states, requiring careful clinical consideration.
Origin
The term is derived from the Greek words angeion, meaning “vessel,” and genesis, meaning “creation” or “birth.” The concept became a major focus in physiological and medical research, particularly in oncology and regenerative medicine, during the mid-20th century. Its application in endocrinology recognizes the influence of hormones like growth factors and sex steroids on vascular dynamics.
Mechanism
This process is primarily regulated by a complex interplay of signaling molecules, notably vascular endothelial growth factor (VEGF) and various growth factors. Hormones can modulate the expression and activity of these pro-angiogenic factors, triggering endothelial cell migration, proliferation, and subsequent tube formation. Adequate oxygen tension and nutrient supply are critical drivers, ensuring the newly formed vessels integrate properly into the existing circulatory system.
