Breast cancer is the leading cause of cancer-related mortality for females worldwide [1]. Improving early screening strategies and understanding the events that lead to tumor initiation have led to demonstrable improvements in clinical outcome. Our previous work revealed a variance in the tumorigenic capacity between different mammary epithelial cell populations in an MMTV-ErbB2 mouse model. In order to greater understand how different mammary epithelial cells influence the tumorigenic capacity in ErbB2-induced breast cancer, we transplanted different cell populations from pre-neoplastic MMTV-ErbB2 female mice into recipient mice for tumorigenic study. We found that different mammary epithelial cells bear different tumorigenic potentials even when induced by the same ErbB2 proto-oncogene. To understand the difference in tumors formed from different epithelial cells, we performed gene expression profiling using these tumors (GSE64487). Several genes were further validated using real-time reverse transcription polymerase chain reaction (RT-PCR). Here we provide further details on the experimental methods and microarray analysis. This data provides a resource to further understanding how different mammary cell populations can initiate ErbB2-driven tumors and the role of these cell populations as putative tumor-initiating cells (TICs).
