Figure 5.

Flow cytometry analyses of the CSCs that were pre-treated with SV119-PEG-AuNCs/DOX for 3 h and then incubated at 37 °C or 40 °C for another 2 h (as a control, the cells were also incubated with SV119-PEG-AuNCs or PEG-AuNCs). The CSCs (ALDHhi population) derived from the mammospheres were labeled using the ALDEFLUOR kit and collected using the BD FACSAria III cell sorter.
