Hematoxylin and eosin stain (H and E stain or HE stain)


Hematoxylin and eosin stain (H&E stain or HE stain) is one of the most commonly used staining techniques in histology and pathology. It is used to reveal the general structure and organization of tissues and cells in various specimens, such as biopsies, surgical resections, autopsies, and cytology smears. H&E stain can help identify normal and abnormal features of tissues and cells, such as inflammation, necrosis, neoplasia, differentiation, and malignancy. H&E stain can also provide clues to the etiology, pathogenesis, and prognosis of various diseases and conditions.
