    • Vessel co-option in primary human tumors and metastases: an obstacle to effective anti-angiogenic treatment? 

      Dønnem, Tom; Hu, Jiangting; Ferguson, M.; Adighibe, Omanma; Snell, Cameron; Harris, Adrian L.; Gatter, Kevin C; Pezzella, F (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Angiogenesis has been regarded as essential for tumor growth and progression. Studies of many human tumors, however, suggest that their microcirculation may be provided by nonsprouting vessels and that a variety of tumors can grow and metastasize without angiogenesis. Vessel co-option, where tumor cells migrate along the preexisting vessels of the host organ, is regarded as an alternative tumor ...
