Angiogenesis is the process through which new blood vessels form from existing ones. This biological mechanism is crucial for growth and development, as it supplies oxygen and nutrients to tissues. It plays a significant role in healing wounds and is essential during pregnancy for the development of the placenta. In addition to its normal functions, angiogenesis is also involved in various diseases. For instance, excessive angiogenesis can contribute to the growth of tumors, as cancer cells require a blood supply to thrive. Researchers study angiogenesis to develop treatments for conditions like cancer and age-related macular degeneration.
