Fig. 5From: TMT-based quantitative proteomic analysis of spheroid cells of endometrial cancer possessing cancer stem cell propertiesIHC results of xenograft tumors transfected with spheroid cells and parent cells of Ishikawa and HEC1A, respectively. A PCNA, VEGF, CD133 and HIF-1α were analyzed by IHC. B The positive staining of PCNA, VEGF, CD133 and HIF-1α were calculated by Image J software. Scale bar, 50 μm. Bar graphs display mean ± SD (* P < 0.05 vs. parent cells, ** P < 0.01 vs. parent cells)Back to article page
