Primary rat hepatocytes in culture fixed and stained for beta-tubulin. The microtubules form a network throughout the cytoplasm. In this image they are seen originating from a brighter and denser re...

Tripolar mitosis in a liver cancer cell line. Normally, dividing cells form a single metaphase plate of paired chromosomes which are pulled apart by opposing microtubule spindles. The Z series, obtai...
