Cervical cancer-initiating cells (CICs) differentially express characteristic genes of CICs and epithelial to mesenchymal transition (EMT). A, Expression of CICs markers in HeLa and SiHa spheroid cells. B, Expression of EMT markers in HeLa and SiHa spheroid cells. Bar graph represents mean fold change (FC) values in spheroid cells compared with those in monolayer, data shown are representative of two independent experiments
