MOESM4 of A pre-existing population of ZEB2+ quiescent cells with stemness and mesenchymal features dictate chemoresistance in colorectal cancer

Additional file 4: Figure S1. Chemoresistance and marker expression of PKH26-positive cells. a Representative flow cytometry analysis of SW480 cells stained with PKH26 and treated with 2,5 μM oxaliplatin (OXA) starting from day 11, as described in Fig. 1a. Cell viability plots obtained with 7-AAD staining are shown below PKH26 plots, and the percentage of viable cells is indicated below each plot. b Representative flow cytometry analysis of EpCAM and PKH26 on xenograft-derived CCSCs 3 weeks upon subcutaneous injection of PKH26-stained cells in NSG mice. IgG, isotype control antibody. c Representative flow cytometry analysis of PKH26 and Ki67 in xenograft-derived EpCAM+ CCSCs at 3 weeks of tumor growth. d Representative flow cytometry analysis of PKH26 and PROMININ1 in xenograft-derived EpCAM+ CCSCs at 3 weeks of tumor growth.
