Cytology is the name given to the branch of biology that deals with the formation, structure and functionality of the cells. Liver cytology specializes in the study of liver cells. The main liver cells are called hepatocytes; however, there are other cells that can be observed in a liver sample such as Kupffer cells (macrophages). The liver is the biggest gland of the body, as well as the biggest organ. It has a wide variety of functions that range from the destruction of old blood cells to the control of the whole metabolism of macromolecules. In the fetus, the liver works as a principal center for hematopoiesis, function that is later replaced by the bone marrow. This hematopoietic function is not normally seen after birth; however, in certain pathological conditions this function may still be seen. It is important to note that the liver is an essential organ and it is the only one in the body that has the ability to regenerate itself after surgery or damage.
