Kuffper cells? These are the fixed macrophages ...
Otherwise you may mean hepatocytes in the liver lobules. These contain many microvilli and carrier proteins facing the space of disse for nutrient exchange.

The functional unit of the liver is known as?
the hepatic lobule is the structural and functional unit of the liver. there are about 50,000 - 1,00,000 lobules in the liver. the lobule is a honey comb like structure and it is made up of liver cells called hepatocytes.
Does the liver have vacuoles which contain cell sap?
Yes, these are called the hepatic lobules. All cells contain cell-sap containing vacuoles.
What type of cell is the Kupffer cell?
Kupffer cells are specialised macrophages that are found in the sinusoids of the liver.
What are the cells that make up the liver?
there are penitential cells in the liver, -narb
What organ contains lobules with sinusoids that lead to a central venous structure?
Brain
How are stem cells trnsplanted?
Stem cells are cells that have not specialised. Specialist cells can only be the one thing that they are specialised for; ie, you cannot turn skin cells into a heart, or liver cells into a brain. Stem cells have not specialised and can therefore become any type of cell. I am not sure how they are stimulated to become one kind or another, but they can. Adult stem cells are not as good as embryonic stem cells, but because harvesting embryonic stem cells requires the destruction of a human embryo it is banned in many countries.
Is a liver lobe the same as a liver lobule?
No, liver lobes and lobules are different. Liver lobes are the grossly (non-microscopically) visible portions of the liver. Most animals have 6 lobes; right lateral, right medial, quadrate, caudate, left medial and left lateral. In some animals these lobes are fused (so it is hard to tell which lobe is which). Lobules are the microscopic units of the liver. The classical lobule is a hexagonal shape with a central vein at the centre and portal triads (portal vein, hepatic artery and bile duct) at some (or all) of the corners. Please see the related links for diagrams of the liver lobes and lobules.
Where are fats stood in the body?
Fat cells known as adipocytes, often in the liver.
What are the host cells in Hepatitis B?
Hepatitis B (HBV) is a partial double stranded DNA virus (Hapadnavirus) that efficiently infects human liver cells, known as hepatocytes. The entry mechanism of HBV in to the human liver cells are yet to be elucidated deeply, but what known is the receptors candidate including the transferrin receptor, the asialoglycoprotien receptor molecule, and endonexin identified as the candidate receptors.The host cells for the hepatitis B are the liver cells called hepatocytes.
What is a nodular liver and cirrhosis of liver?
When there is damage to the liver, it attempts to repair itself. The remaining cells (mainly hepatocytes, but also oval cells) - undergo mitotic division in order to replace damaged or dead cells. This process is known as hyperplasia. When hyperplasia occurs in the liver, it results in nodular formations of new cells. A cirrhotic liver is an end-stage liver. It cannot be repaired, and if the person is to live they will need a transplant. A cirrhotic liver will be diffusely (all-over) covered with nodules, where the liver has attempted to regenerate. It will also have scar-tissue and fibrosis as a result of the damage to the liver.
Why do some cells have more mitochodria?
Cells such as liver cells, sperm cells and muscle cells have more mitochondria. This is because they are more metabolically active and need a plentiful supply of ATP (adenosine triphosphate) for metabolic processes. For example, many chemical processes occur in liver cells and sperm cells are known for movement.
What is the tissues of the liver and their function?
Liver tissue is made up of two types of cells: karat parenchymal and non-parenchymal cells. The karat parenchymal cells are known as hepatocytes. There are several types of non-parenchymal cells: Sinusoidal hepatic endothelial cells, Kupffer cells and hepatic stellate cells. The liver has a number of functions, including synthesizing hormones and breaking down substances for metabolization by the body's various systems.
