The most commonly used stain in histology is a combination of hematoxylin and eosin (often abbreviated H&E). Hematoxylin is used to stain nuclei blue, while eosin stains the cytoplasm and the extracellular connective tissue matrix of most cells pink. There are hundreds of various other techniques which have been used to selectively stain cells.
It is also at this step that the pathologist selects areas that will be processed for histopathology. The eye can sometimes be aided with a magnifying glass or a stereo microscope, especially when examining parasitic organisms. Histopathology – the microscopic examination of stained tissue sections using histological techniques.
The ependyma is made up of ependymal cells called ependymocytes, a type of glial cell. These cells line the ventricles in the brain and the central canal of the spinal cord, which become filled with cerebrospinal fluid. These are nervous tissue cells with simple columnar shape, much like that of some mucosal epithelial cells. [2]
Micrograph of a GFAP immunostained section of a brain tumour.. In biochemistry, immunostaining is any use of an antibody-based method to detect a specific protein in a sample. . The term "immunostaining" was originally used to refer to the immunohistochemical staining of tissue sections, as first described by Albert Coons in 1941.
Histopathology is the branch of histology that includes the microscopic identification and study of diseased tissue. [ 5 ] [ 6 ] It is an important part of anatomical pathology and surgical pathology , as accurate diagnosis of cancer and other diseases often requires histopathological examination of tissue samples.

In histopathology, a palisade is a single layer of relatively long cells, arranged loosely perpendicular to a surface and parallel to each other. [1] A rosette is a palisade in a halo or spoke-and-wheel arrangement, surrounding a central core or hub. [ 2 ]
Brain cells make up the functional tissue of the brain. The rest of the brain tissue is the structural stroma that includes connective tissue such as the meninges , blood vessels , and ducts. The two main types of cells in the brain are neurons , also known as nerve cells, and glial cells , also known as neuroglia. [ 1 ]
