The chemical carcinogen 7,12-dimethylbenz[a]anthracene (DMBA) has been used for many decades to induce skin, mammary, and ovarian tumors in mice. There are however a wide range of doses and treatment regimens in the literature that sometimes confound comparative interpretations of different studies. Here we describe a proven method to generate in vivo DMBA-mediated murine mammary tumors to enable consistent studies of the cell targeted role of genes of interest during this process.
