Fig. 1. Effects of chemotherapy drugs (LC50) on the actin structure in HeLa Kyoto cervical cancer cells. (A) The control sample. (B) Cells incubated with cytochalasin D. (C) Cells incubated with cisplatin. (D) Cells incubated with paclitaxel
Fluorescence TIRF microscopy. Staining with SiR-actin (Spirochrome, Switzerland) and Hoechst 33342 (Thermo Fisher Scientific, USA). The actin cytoskeleton and the nuclei are shown in grey and blue, respectively. The scale bar is 10 μm.
