Interestingly, while this finding was consistent across all the models and genetic backgrounds studied, the changes in recruitment of the granulocytic (Ly6G+Ly6Clow) or monocytic (Ly6C+ Ly6G−) subpopulations to mammary tumours were distinct, depending on the organ (mammary gland vs. lungs) and on the model in which CAFs were manipulated. Here, TBX1 is linked to breast cancer.
