So a tumor expresses chemokine receptors, and another organ -- a distant organ somewhere in the body -- will have the corresponding chemokines, and the tumor will see these chemokines and migrate towards it.
Tumor ispušta svoje receptore za kemokine, a drugi organ, daleki organ negdje u tijelu, ima kemokine koji se podudaraju; tumor će vidjeti te kemokine i otputovati prema njima.
