Vascularisation is when blood vessels form in tissues or organs to supply them with oxygen and nutrients.
Without it, tissues wouldn’t get the nutrients that they need to work and stay healthy.
Scientists are currently working on ways to grow new blood vessels to help with tissue engineering and healing injuries.
Scientists are now developing therapies that block angiogenesis, cutting off the tumour blood supply.
[citation needed] This has become a strategy in cancer treatments, with medications like bevacizumab that are being used to shrink tumours by preventing blood vessel growth.
