Breast cancer, and especially the aggressive subtypes such as triple-negative breast cancer (TNBC), remain one of the deadliest cancers in women worldwide. Despite their positive effects in preclinical animal models, most of the new therapeutics fail in clinical trials, which has resulted in a high demand for preclinical models that are more representative for the human situation. As an answer to this urgent need, our group has developed an immunocompetent intraductal mouse model for TNBC that relies on the injection of triple-negative mouse mammary tumor cells through the teat canal into the mammary ducts of syngeneic and lactating female mice. This model has been characterized during my PhD and recapitulates the complete human TNBC process from early ductal carcinoma in situ (DCIS) to late invasive carcinoma and metastasis. The immunological responses that accompany the tumor progression in this model have also been evaluated and are highly comparable to the tumor immunology found in TNBC patients. The intraductal model is now being explored in collaboration with industrial and academic partners for preclinical testing of novel drugs before entry into clinical trial. This translational research has already provided promising data.
