As expected, these cells expressed chemokine receptors important for prostate cancer dissemination in humans (CXCR1, CXCR2, CXCR4 and CCR2)9 as well as CCR3 whose function in prostate cancer chemotaxis has been recently described in vitro13 (Fig. 1b and Supplementary Fig. 1a). Here, CCR3 is linked to prostate carcinoma.
