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.
Free's discography consists of six studio albums, two live albums, 18 compilation albums, one EP, 16 singles and two video albums. The band released their debut album Tons of Sobs in 1969. [ 1 ] The album entered the US Billboard 200 chart at number 197. [ 2 ]
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.
In general, a fine-needle aspiration can be done anywhere it is safe to put a needle, including liver, lung, kidney, and superficial masses. Proper cytopathology technique takes time to master. Cytotechnologists and cytopathologists can assist clinicians by assisting with sample collection.
Acanthocytes, from peripheral blood, under light microscopy. Note the irregularly shaped, non-circular cells in the image. Acanthocyte (from the Greek word ἄκανθα acantha, meaning 'thorn'), in biology and medicine, refers to an abnormal form of red blood cell that has a spiked cell membrane, due to thorny projections.
The Terminologia Histologica (TH) is the controlled vocabulary for use in cytology and histology. [1] [2] In April 2011, Terminologia Histologica was published online [3] by the Federative International Programme on Anatomical Terminologies (FIPAT), the successor of FCAT. It was intended to replace Nomina Histologica.
