(A) Representative microangiogram from the control mice taken one week after transplantation. Growth of the tumor was not prominent. However, a small feeding artery from the mammary artery could be identified (white arrow). (B) Representative microangiogram from the control mice taken four weeks after transplantation. Tumor growth was marked, with a horizontal tumor diameter of approximately 15 mm (visual field: 20 × 30 mm). (C) Representative microangiogram from the control mice taken four weeks after transplantation. The tumor was fed not only by the mammary and axillary arteries but also by the pulmonary artery, which contains low-oxygen blood. (D) Representative microangiogram at four weeks after transplantation from the group treated with VEGF antibody. Growth of the networks of tumor feeding arteries is obviously suppressed compared with (B) from a control mouse.
