Blood vessel formation. Illustration showing malignant (cancerous) tumour cells promoting the formation of new blood vessels, a process known as angiogenesis. The tumour cells release angiogenic growth factor proteins that bind to endothelial cells in nearby blood vessels and encourage the growth of new blood vessels from the existing ones. These blood vessels provide the tumour with oxygen and nutrients. | |
