Fig. 4. Mitosis is not disrupted in Cp190 mutant larval brain cells. The distribution of microtubules (black and white panels, red in merged images), CP190 (green), and DNA (blue) in typical wild type (WT) and Cp1902 mutant larval brain cells in metaphase (left panels) and anaphase (right panels). Mitotic spindle organisation appears normal in the mutant cells even though CP190 is no longer detectable at centrosomes.
