TSLP and breast carcinoma: In one model they crossed the MMTV-polyoma middle T (PyMttg) breast cancer-prone with the K14-TSLPtg mice (K14-TSLPtgPYMttg), whereas in the other model WT mice were topically treated with calcipotriol, which is known to induce TSLP expression in mouse keratinocytes (62).
