From: CCL1 is a major regulatory T cell attracting factor in human breast cancer
CCL1 and FoxP3 are intensively expressed in human invasive breast cancer. Tissue microarrays (TMAs) of mammary carcinoma and non-malignant control samples have been immunohistochemically stained for the indicated proteins. Representative sections for (a) CCL1, (b) CCL22 and (c) FoxP3 are shown. (d) TMAs of breast cancer and healthy breast tissue were analyzed for the number of positive cells/mm2. For statistical analysis the Mann-Whitney-U-Test was used
