| Research Abstract |
To obtain monoclonal antibodies specifically targeting cancer stem cells, we immunized rat with induced cancer stem cells (iCSC) followed by the production of hybridomas. By using iCSC and breast cancer cell lines, we selected two monoclon al colones that only recognize iCSC but not brest cancer cell line. Protein array analysis revealed that ABL1 could be a target of the monoclonal antibodies. When iCSCs were treated with an ABL inhibitor, imatinib, self-renewal property of iCSCs was inhibited.
