<p><b>A</b> Ciliated hTERT-RPE1 (human retinal pigmented epithelial cells and HK2 human kidney cells were stained with antibody to Plk1 (green), acetylated α-tubulin (orange), and γ-tubulin (red), and treated with DAPI to visualize DNA (blue). The scale bar represents 5 µm. <b>B</b> Ciliated hTERT-RPE1 cells and HK2 cells were stained with antibody to acetylated α-tubulin (orange), γ-tubulin (red), to NPHP1 or Plk1 as indicated (green), and with DAPI to visualize DNA (blue). The third row shows merged signals from staining with antibody to Plk1 (orange), NPHP1 (green) acetylated α-tubulin (orange), γ-tubulin (red) and DAPI was used to visualize DNA (blue). The scale bar represents 5 µm.</p
