Confocal microscopy gives researchers a powerful way to observe cell division, a tightly controlled process whose errors can drive genomic instability and cancer. It reveals how centrosomes, microtubules, chromosomes, and regulators like PLK1 and MOB1 behave during mitosis, helping scientists track spindle assembly, chromosome alignment, and cytokinesis in real time. By visualizing these proteins’ dynamic roles, researchers can identify where regulatory failures occur and how they contribute to tumor formation. This high‑resolution approach not only clarifies how mitotic mechanisms maintain genomic stability but also highlights pathways that could be targeted for future cancer therapies.
