Cirrhosis. Coloured scanning electron micrograph of a human liver cell (red-brown), also known as hepatocyte, showing abnormal features caused by cirrhosis. It is a disease in which bands of connective tissue (pale orange upper centre) break up the normal structure of the liver severely impairing its functions. The surface of the liver cell (upper centre right) is abnormal showing irregular microvilli and larger evaginations. Two activated macrophages (Kupffer cells, yellow) are seen in a capillary (blue). The wall of the capillary (pale purple) is very thick and fenestrated. Magnification: x2250 at 6x7cm size.
