Liver tissue hepatocytes. Transmission electron micrograph (TEM) of a section through liver tissue and the nuclei of two liver cells (hepatocytes). One of the hepatocytes has two nuclei (left, binucleate). Although this is relatively common in mammals, the significance of such polyploidal hepatocytes is not understood. Hepatocytes store glycogen (indicated by the dense particulate material in the cytoplasm). They also have a high abundance of both rough and smooth endoplasmic reticulum.
