The liver parenchyma is the functional tissue of the organ made up of around 80% of the liver volume as hepatocytes. The other main type of liver cells are non-parenchymal. Non-parenchymal cells constitute 40% of the total number of liver cells but only 6.5% of its volume. [11]
For example, the gland's tissue that makes the hormones is the parenchyma, whereas the stroma includes the nerves that innervate the parenchyma, the blood vessels that oxygenate and nourish it and carry away its metabolic wastes, and the connective tissues that provide a suitable place for it to be situated and anchored.
The name is derived from the fact that the cells undergoing this form of cell death increase in size . It is generally considered a form of apoptosis , [ 1 ] and is a descriptor used in the context of inflamed fatty liver ( steatohepatitis ) [ 2 ] (which may be due to obesity or alcohol ), as well as viral hepatitis.
The epithelial liver cords and biliary system growing out into the septum transversum differentiate into parenchyma. Hematopoietic cells (present in the liver in greater numbers before birth than afterward), Kupffer cells, and connective tissue cells originate in the mesoderm. The pancreas develops from a ventral bud and a dorsal bud that later ...
In liver pathology, a ground glass hepatocyte, abbreviated GGH, is a liver parenchymal cell with a flat hazy and uniformly dull appearing cytoplasm on light microscopy. The cytoplasm's granular homogeneous eosinophilic staining is caused by the presence of HBsAg.
It forms a protective covering on the leaf vein and consists of one or more cell layers, usually parenchyma. Loosely-arranged mesophyll cells lie between the bundle sheath and the leaf surface. The Calvin cycle is confined to the chloroplasts of these bundle sheath cells in C 4 plants. C 2 plants also use a variation of this structure. [1]
The cells which make up stroma tissues serve as a matrix in which the other cells are embedded. [2] Stroma is made of various types of stromal cells. Examples of stroma include: stroma of iris; stroma of cornea; stroma of ovary; stroma of thyroid gland; stroma of thymus; stroma of bone marrow; lymph node stromal cell; multipotent stromal cell ...
Although sclereids are variable in shape, the cells are generally isodiametric, prosenchymatic, forked, or elaborately branched. They can be grouped into bundles, can form complete tubes located at the periphery, or can occur as single cells or small groups of cells within parenchyma tissues. An isolated sclereid cell is known as an idioblast.
