basophil granulocytes; anterior pituitary basophils; An abnormal increase in basophil granulocytes is therefore also described as basophilia. [2] The opposite of basophilic structures are acidophilic structures, also called eosinophilic. These structures contain many positive charges and are thus strongly stained by anionic dyes like eosin.
In the anterior pituitary, the term "acidophil" is used to describe two different types of cells which stain well with acidic dyes.. somatotrophs, which secrete growth hormone (a peptide hormone)
An anterior pituitary basophil is a type of cell in the anterior pituitary which manufactures hormones. It is called a basophil because it is basophilic (readily takes up bases), and typically stains a relatively deep blue or purple. [1] These basophils are further classified by the hormones they produce.
Acidophile (or acidophil, or, as an adjectival form, acidophilic) is a term used by histologists to describe a particular staining pattern of cells and tissues when using haematoxylin and eosin stains. Specifically, the name refers to structures which "love" acid, and take it up readily.
There are four types of granulocytes (full name polymorphonuclear granulocytes): [3] Basophils; Eosinophils; Neutrophils; Mast cells; Except for the mast cells, their names are derived from their staining characteristics; for example, the most abundant granulocyte is the neutrophil granulocyte, which has neutrally staining cytoplasmic granules.
The anterior pituitary (also called the adenohypophysis or pars anterior) is a major organ of the endocrine system.The anterior pituitary is the glandular, anterior lobe that together with the (posterior pituitary, or the neurohypophysis) makes up the pituitary gland (hypophysis) which, in humans, is located at the base of the brain, protruding off the bottom of the hypothalamus.
Acidophiles or acidophilic organisms are those that thrive under highly acidic conditions (usually at pH 5.0 or below [1]). These organisms can be found in different branches of the tree of life , including Archaea , Bacteria , [ 2 ] and Eukarya .
A basophil granulocyte is surrounded by lightly staining eosinophilic erythrocytes in an H&E staining. Eosinophilic (Greek suffix -phil-, meaning loves eosin) is the staining of tissues, cells, or organelles after they have been washed with eosin, a dye. Eosin is an acidic dye for staining cell cytoplasm, collagen, and muscle fibers.
