Angiogenesis is the process through which new blood vessels form from existing ones. This biological mechanism is essential for growth, development, and healing in the body. It plays a crucial role in supplying oxygen and nutrients to tissues, especially during wound healing and in response to physical activity. In addition to its normal functions, angiogenesis can also contribute to disease. For instance, excessive angiogenesis is often associated with cancer, as tumors require a blood supply to grow and spread. Understanding this process is vital for developing treatments that can inhibit abnormal blood vessel formation in various medical conditions.
