Centrioles via Centrin
Figure. Centrin and DNA through cell cycle. Single plane images of hiPS cells expressing mTagRFP-T–tagged centrin (green) and labeled with Hoechst dye (DNA; blue) imaged on a spinning-disk confocal microscope. Cells labeled A-F represent different stages of the cell cycle (see diagram). A) G1-phase, B) early S-phase, C) later S-phase, D) G2/M-phase and E–F) M-phase contain centrioles at distinguishable stages of duplication (see zoomed in images and cell cycle diagram).
