‘Chase and run’ cell movement mechanism explains process of metastasis
Published in Nature Cell Biology, the new study focuses on the process that occurs when cancer cells interact with healthy cells in order to migrate around the body during metastasis. Scientists know that cancer cells recruit healthy cells and use them to travel long distances, but how this process takes place and how it could be controlled to design new therapies against cancer remains unknown. Now, using embryonic cells called ‘neural crest cells’ (which are similar to cancer cells in term of their invasive behaviour) and placode cells which are the precursors for cranial nerves (the equivalent to healthy cells) researchers at UCL have started to unravel this process. They have found that when neural crest cells are put next to placode cells they undergo a dramatic transformation and start ‘chasing’ the placode cells…
