Cytology is the name given to the branch of biology that deals with the formation, structure and functionality of the cells. [1] 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). [2]
For these purposes, hepatocytes are usually isolated from animal or human [8] whole liver or liver tissue by collagenase digestion, which is a two-step process. In the first step, the liver is placed in an isotonic solution, in which calcium is removed to disrupt cell-cell tight junctions by the use of a calcium chelating agent .
A perianal gland tumor is a type of tumor found near the anus in dogs that arises from specialized glandular tissue found in the perineum. [1] It is also known as a hepatoid tumor because of the similarity in cell shape to hepatocytes (liver cells). It is most commonly seen in intact dogs and is the third most common tumor type in intact male ...
Articles reating to the liver, a major organ, only found in vertebrates, which performs many essential biological functions such as detoxification of the organism, and the synthesis of proteins and biochemicals necessary for digestion and growth.
Tumors that develop within the liver may be either benign (noncancerous) or malignant (cancerous). Tumors can start in the liver, or spread to the liver from another cancer in the body. Malignant liver tumors have been reported to metastasize to other organs such as regional lymph nodes, lungs, kidneys, pancreas, spleen and others.

Effusion cytology – concerning fluids collections, especially within the peritoneum, pleura and pericardium; Breast cytology – principally concerning the female breast; Vaginal cytology - principally concerning non-human mammals
The vault or vault cytoplasmic ribonucleoprotein is a eukaryotic organelle (a structure in the cells of multicellular organisms) whose function is not yet fully understood. . Discovered and isolated by Nancy Kedersha and Leonard Rome in 1986, [2] vaults are cytoplasmic structures (outside the nucleus) which, when negative-stained and viewed under an electron microscope, resemble the arches of ...
