Liver cells. Scanning electron micrograph (SEM) of liver cells or hepatocytes. Several of the cells (for example, at upper left) are undergoing cell division. Hepatocytes are specialised epithelial cells and the most abundant cells in the liver. They are arranged in units known as lobules, each lobule surrounding a vein (not seen). Hepatocytes are involved with the various functions of the liver, including metabolism, detoxification of the blood and bile production. Magnification: x3900 at 6.5x8.5 inch size.
