Angiogenesis is required for normal development to proceed H

Angiogenesis is required for normal development to proceed. However, angiogenesis is also required to allow tumors to become metastatic. Explain how angiogenesis is involved in these two diverse pathways and give two examples for its role in normal development and two examples for its role in cancer.

Solution

Angiogenesis is the process of formation of blood vessels. For an individual to have normal development, it is essential for blood vessels to be formed, thus angiogenesis. In case of tumor formation, the new cells formed also need to be supplied with oxygen, nutrients and energy, thus they also need blood vessels for circulation.

In normal development:

In case of cancer:
