Basophils contain large cytoplasmic granules which obscure the cell nucleus under the microscope when stained. However, when unstained, the nucleus is visible and it usually has two lobes . [ 7 ] The mast cell , another granulocyte, is similar in appearance and function.
A Basophil granulocyte stains dark purple upon H&E staining. Basophilic is a technical term used by pathologists. It describes the appearance of cells, tissues and cellular structures as seen through the microscope after a histological section has been stained with a basic dye. The most common such dye is haematoxylin.
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.
White cells are found in the buffy coat, a thin, typically white layer of nucleated cells between the sedimented red blood cells and the blood plasma. The scientific term leukocyte directly reflects its description. It is derived from the Greek roots leuk-meaning "white" and cyt-meaning "cell".
A white blood cell differential is a medical laboratory test that provides information about the types and amounts of white blood cells in a person's blood. The test, which is usually ordered as part of a complete blood count (CBC), measures the amounts of the five normal white blood cell types – neutrophils, lymphocytes, monocytes, eosinophils and basophils – as well as abnormal cell ...
These cells also have a limited ability to participate in phagocytosis, [20] they are professional antigen-presenting cells, they regulate other immune cell functions (e.g., CD4+ T cell, dendritic cell, B cell, mast cell, neutrophil, and basophil functions), [21] they are involved in the destruction of tumor cells, [17] and they promote the ...
Light micrograph of a moss's leaf cells at 400X magnification. The following outline is provided as an overview of and topical guide to cell biology: . Cell biology – A branch of biology that includes study of cells regarding their physiological properties, structure, and function; the organelles they contain; interactions with their environment; and their life cycle, division, and death.
The function of promyelocytes are closely linked to their differentiation into mature granulocytes, which include neutrophils, eosinophils, and basophils. [citation needed] These functions are essential for innate immunity and host defense mechanisms, including phagocytosis, inflammation, and immune surveillance.
