Centriole movement in mouse mammary epithelial cells during cytokinesis. During cytokinesis, centrioles show increased mobility and either one centriole or the complete centrosome is frequently associated with the nuclear envelope. After abscission centrioles increase their mobility and frequently detach from the nuclear envelope. The images show an overlay of DIC, green and red recordings to show centriole-specific centrin1-EGFP localization together with the intercellular bridge marker α-Tubulin-mCherry. White arrows indicate centrioles by the nuclear envelope.
