CD24 is involved in the anchorage‐independent growth of lung cancer cells. A, CD24 mRNA expression in HARA and HARA‐B4 cells. Data are shown as relative values based on that in HARA. B, Phase contrast images showing the survival of HARA (left) and HARA‐B4 (right) cells under normal conditions for 1 wk after 2‐wk culture in ultra‐low attachment culture conditions. Scale bar = 50 μm. C, CD24 mRNA expression in HARA and HARA‐B4 cells at the indicated days under anchorage‐independent conditions. Data are shown as relative values based on that in HARA cells at day 1, and are presented as the mean ± SD (n = 3). **P < .01
