Effect of CELF1 gene knockdown on the colony forming ability of lung cancer cells. (A, B) The cancer cell colonies under light, bright field and fluorescence microscopy. The colonies were stained with Giemsa staining. The images show comparison of the size of colonies in normal, CELF1-silenced and non-silenced lung cancer cells. (C, D) The number of colonies in normal, CELF1-silenced and non-silenced lung cancer cells. The values represents the mean from three independent experiments; bars represent SD. **P < 0.01, ***P < 0.001 compared with controls.
