Definition

1. Noun:
   • The formation of new blood vessels: "Angiogenesis" refers to the physiological process through which new blood vessels form from pre-existing vessels. This is a normal and vital process in growth, development, and wound healing, but it also plays a role in certain diseases.

Usage Examples

• Noun:
  • The drug inhibits tumor growth by blocking angiogenesis. (The medication stops the cancer from growing by preventing the formation of new blood vessels that feed it.)
  • Angiogenesis is a crucial step in the healing of a deep wound. (The formation of new blood vessels is an essential part of the recovery process for a serious injury.)

Advanced Usage

• Pathological angiogenesis: This term describes the abnormal formation of new blood vessels, which can contribute to diseases like cancer and macular degeneration.
  • Researchers are studying ways to control pathological angiogenesis. (Scientists are investigating methods to regulate the harmful growth of new blood vessels in diseases.)
• Therapeutic angiogenesis: This refers to the clinical strategy of promoting blood vessel growth to treat conditions like coronary artery disease.
  • The goal of therapeutic angiogenesis is to improve blood flow to damaged heart tissue. (The aim of this medical approach is to encourage new vessel growth to restore circulation to the heart.)

Variants and Related Words

• Angiogenic (adj): Relating to or promoting the formation of new blood vessels.
  • The tumor releases angiogenic factors. (The cancer produces substances that stimulate new blood vessel growth.)
• Anti-angiogenesis (n): A treatment strategy designed to stop the formation of new blood vessels, typically to starve a tumor.
  • Anti-angiogenesis therapy is a type of cancer treatment. (This is a form of cancer care that works by blocking vessel growth.)

Synonyms

• Neovascularization: The formation of new functional microvascular networks. (Note: This is a more clinical synonym often used in medical contexts.)
• Vasculogenesis: The formation of blood vessels from endothelial progenitor cells, which is a related but distinct process from angiogenesis.

Related Phrases and Compounds

• Angiogenesis inhibitor: A substance that inhibits the growth of new blood vessels.
  • The patient was treated with an angiogenesis inhibitor. (The individual received a drug that blocks new blood vessel formation.)
• Angiogenic switch: The point at which a tumor begins to recruit and form its own blood supply.
  • Understanding the angiogenic switch is key to preventing cancer progression. (Comprehending the moment a tumor starts growing its own vessels is crucial for stopping its spread.)
