Figure 3From: Evaluation of stem-like side population cells in a recurrent nasopharyngeal carcinoma cell lineSP cells grow at a slower rate compared to NSP cells. (A) Upon relabelling with Hoechst 33342 on day 21 post-sorting, recultured SP cells had divided asymmetrically into SP and NSP phenotypes. Recultured NSP cells had poorer asymmetric division ability. (B) Impedance-based cell growth assay indicated that the normalized growth rate for SP cells was lower than NSP cells.Back to article page
