(A) Growths in BALB/c nude mice after inoculation with CD133+/CD44+ cells taken from DU145 cultures. (B) Xenograft tumor growth curve for week 1 to 8 for all mice. At 8 weeks, xenograft tumor volume in CD133+/CD44+ DU145 cells was bigger than that of parental DU145 cells (CD133+/CD44+ cells versus the parental cells, 813.26 ± 122.66 mm3 versus 443.87 ± 73.17 mm3, * p < 0.001). (C) Histological analysis of subcutaneous tumors using hematoxylin and eosin staining shows cancer cell-specific features (irregularly packed tumor cells, hyperchromatic nuclei, prominent nucleoli and many mitotic cells). (D) Immunofluorescence double-staining visualized by confocal microscopy. CD133 is shown in red and CD44 in green.
