mt p53 promotes the symmetric cell division of cisplatin-resistant stem cell-like NSCLC cells. (a) Forced expression of wt p53 and mt p53 in p53 null H1299/CisR cells. Western blot analysis of lysates from H1299/Cr, H1299/Cr-wt-p53, and H1299/Cr-mt-p53 cells using an anti-p53 antibody. GAPDH was used as an internal control. (b, c) Fluorescence microscopy for the analysis of the division of CD44+/CD90+ LCSCs isolated from H1299/Cr-wt-p53 and H1299/Cr-mt-p53 cells following cell seeding.
