Nally, stromal cells may have played a role in the induction of DC-SCRIPT in the epithelial tumor cells. In analogy, ESR2 is - apart from breast cancer epithelial tumor cells - also expressed in adjacent infiltrating lymphocytes, fibroblasts, and endothelial cells [3]. Interestingly, in tumors that express relatively high ESR2 mRNA levels and that in general have a higher stromal content, DC-SCRIP
