Fig. 1From: TMT-based quantitative proteomic analysis of spheroid cells of endometrial cancer possessing cancer stem cell propertiesSpheroid cells showed increased ability of colony forming, subsphere forming and drug resistance. A Colony forming assay and quantitative efficiency of the parent cells and spheroid cells. B Secondary spheroid body formation assay and number of secondary spheroids of the parent cells and spheroid cells. C Rates of resistance to dox were assessed using CCK8 assay for Ishikawa. D Rates of resistance to dox were assessed using CCK8 assay for HEC1A (* P < 0.05, ** P < 0.01, *** P < 0.001)Back to article page
