A human mammary epithelial cell stained to visualize the microtubule spindles (α-tubulin), centrioles (centrin 2), and chromosomes (DAPI). The image is represented by four different color combinations, modified using Photoshop software. Splitting of centriole pairs in primary cells leads to multipolar spindles and causes mis-segregation of chromosomes during mitosis (aneuploidy). See McDermott et al.
