The somatic mesoderm, which is adjacent to the ectoderm and amnion, gives rise to the bones, ligaments, blood vessels, and connective tissue of the limbs.
Blood supply and cancer. As the tumour gets bigger, the centre of it gets further and further away from the blood vessels in the area where it is growing. So the centre of the tumour gets less and less of the oxygen and the other nutrients all cells need to survive.Like healthy cells, cancer cells cannot live without oxygen and nutrients. So they send out signals, called angiogenic factors, that encourage new blood vessels to grow into the tumour.This is called angiogenesis. Without a blood supply, a tumour can't grow much bigger than a pin head.Once a cancer can stimulate blood vessel growth, it can grow bigger and grow more quickly. It will stimulate the growth of hundreds of new capillaries from the nearby blood vessels to bring it nutrients and oxygen.View a transcript of the video about how cancer gets a blood supply.o the centre of the tumour gets less and less of the oxygen and the other nutrients all cells need to survive.
