It is particularly noteworthy that 6 chemokine receptors in GO term “chemokine binding”, including CXCR4, CCR5, CCR1, CCRL2, CMKLR1 and A2M, are specific expressed in FGFR2+ fibrocytes before arriving in tumor sites suggesting their possible roles in fibrocyte recruitment. This evidence concerns the gene CMKLR1 and neoplasm.
