exists and is an alternate of . In biology, adaptation is the process by which an organism changes to become better suited to survive in their environment. It can also refer to a physical or genetic trait that helps an organism to be better suited to survive in their environment.
Angiogenesis is the physiological process through which new blood vessels form from pre-existing vessels. This is distinct from vasculogenesis, which is the de novo formation of endothelial cells from mesoderm cell precursors.owever, it is also a fundamental step in the transition of tumors from a benign state to a malignant one, leading to the use of angiogenesis inhibitors in the treatment of cancer.
When it has reached 1 to 2mm across, it needs to grow its own blood vessels so that it can continue to get bigger. The growth of new blood vessels is called angiogenesis. Anti angiogenic drugs are biological therapies that stop tumours from growing their own blood vessels. This is a quite a new way of treating cancers. Researchers are still learning how best to use these treatments.
