What tissue components does H&E stain?
The H&E stain provides a comprehensive picture of the microanatomy of organs and tissues. Hematoxylin precisely stains nuclear components, including heterochromatin and nucleoli, while eosin stains cytoplasmic components including collagen and elastic fibers, muscle fibers and red blood cells.

What tissue components does H&E stain?

What color is liver tissue?
Liver is usually red-brown in colour, so white tissue may indicate capsular tissue or the presence of tumour.
What tissues stain blue with H&E stain?
Cell nuclei
Examples of H&E stained tissues Cell nuclei (blue-purple), red blood cells (bright red), other cell bodies and extracellular material (pink), and air spaces (white). Muscle tissue, cell nuclei (blue-purple), extracellular material (pink).
What colour does H&E stain connective tissue?
Hematoxylin has a deep blue-purple color and stains nucleic acids by a complex, incompletely understood reaction. Eosin is pink and stains proteins nonspecifically. In a typical tissue, nuclei are stained blue, whereas the cytoplasm and extracellular matrix have varying degrees of pink staining.
What does H&E staining do?
H and E staining helps identify different types of cells and tissues and provides important information about the pattern, shape, and structure of cells in a tissue sample. It is used to help diagnose diseases, such as cancer. Also called hematoxylin and eosin staining.
Why is hematoxylin and eosin H&E staining used routinely in histopathology?
Hematoxylin and Eosin (H&E) staining is used routinely in histopathology laboratories as it provides the pathologist/researcher a very detailed view of the tissue. It achieves this by clearly staining cell structures including the cytoplasm, nucleus, and organelles and extra-cellular components.
What is liver stain?
The stain imparts a blue color to collagen against a red background of hepatocytes and other structures. It stains type 1 collagen that is normally present in the portal tracts and vessel walls, but also highlights the presence and distribution of reactive fibrosis as a result of liver injury.
What is staining of a liver biopsy?
Aside from standard H&E, the most common special stains used to assess liver biopsies include trichrome, iron, PAS-D, reticulin, and copper. Trichrome is used to assess/stage fibrosis and it stains collagen blue.
What is basophilic and eosinophilic?
Eosinophils (basic components that like acids) are dyed red by the acid stain, eosin. “Basophils” (acid that like base components) are dyed blue by the basic stain, hematoxylin.
Are proteins eosinophilic or basophilic?
Basophilic and acidophilic staining. Proteins and other components in the cytoplasm are basic, and will bind to acidic dyes. Another way of saying this is that cytoplasmic proteins are acidophilic (acid liking – i.e. bind to acidic dyes). Basic dyes react with anionic or acidic components in cells.
What is the liver?
The liver is an organ about the size of a football that sits just under your rib cage on the right side of your abdomen. The liver is essential for digesting food and ridding your body of toxic substances.
What is hepatic histology?
Hepatic Histology: Hepatocytes VIVO Pathophysiology Digestive System> Liver Hepatic Histology: Hepatocytes Hepatocytes are the chief functional cells of the liverand perform an astonishing number of metabolic, endocrine and secretory functions. Roughly 80% of the mass of the liver is contributed by hepatocytes.
How much of the mass of the liver is contributed by hepatocytes?
Roughly 80% of the mass of the liver is contributed by hepatocytes. In three dimensions, hepatocytes are arranged in plates that anastomose with one another.
Why is the liver called the heaviest part of the body?
Rosenthal hypothesized that the term’s usage to describe heaviness comes perhaps from the liver being the heaviest of all body parts in some farm animals or in humans. ^ “Foie”.
