Figure 2. Ki-67 localization throughout the cell cycle.
HeLa S3 cells were stained with anti-Ki67 antibodies (green) and DAPI to visualize DNA (blue), illustrating different Ki-67 localizations across the cell cycle. In mitotic cells, Ki-67 coats the condensed chromosomes as the foundation of the perichromosomal layer. As cells exit mitosis and enter early G1 phase, small puncta of Ki-67 leave the decondensing chromosomes. These then coalesce at the periphery of the reformed nucleoli as G1 phase progresses. Scale bar, 10 μm.
