Description
The aim of this study is to elucidate the functional significance of polyploidy in triple-negative breast cancer (TNBC). We isolated and characterized the diploid and polyploid subpopulations occurring de novo or induced by chemotherapy in TNBC cell lines. Preliminary findings indicate that polyploid cells divide slower than the diploid cells and display resistance to mitotic inhibitor, docetaxel. In our future studies, we will examine these subpopulations for differences in their tumorigenic potential and role in tumor recurrence.
