Cancer cell injected into an isloated rabbit thyroid gland kept alive with a nutrient solution fail to link up to the organ's blood vessels, the tumours grow to 1-2 mm in diameter. When injected into live animals, the same tumors become infiltrated with blood vessels and grow to enormous size.
Cancer cells placed in the anterior chamber of rabbit's eye, where there are o blood vessels, die before they reach enormous size. In cotrast, cancer cells placed on the iris become infiltrated with blood vessels and the tumors grow to 1-2 mm in diameter.
