Figure Lengend Snippet: CD133 + SP cells exhibit high self-renewal capacity. (A) A clone formation efficiency assay revealed that the total number of tumor spheres generated by the CD133 + SP cells were significantly higher, compared with the number generated by the MP cells. (B) Quantification of the results of reverse transcription-quantitative polymerase chain reaction analysis showed that the relative mRNA expression levels of Oct-4, EpCAM, Sox-2, Bmi-1 and Nestin were significantly upregulated in the CD133 + SP cells, compared with the MP cells. (C) Fluorescence microscopy revealed that the CD133 + SP cells exhibited more positive CD44 fluorescence and EpCAM stem cell proteins, whereas this fluorescence was not enriched in the MP cells. Magnification, ×400. Data are presented as the mean ± standard error of the mean. ** P<0.01, vs. SP. Oct-4, octamer-binding transcription factor-4; EpCam, epithelial cell adhesion molecule; Sox-1, (sex determining region Y)-box 2; Bmi-1, B-cell-specific Moloney murine leukemia virus insertion site-1; CD. cluster of differentiation; SP, side population; MP, main population.
Article Snippet: The cells were incubated with rabbit anti-CD133 fluorescein isothiocyanate (FITC)-conjugated antibody (dilution, 1:500; cat. no. orb15325; Biorbyt, Cambridge, UK) for 30 min.
