A band cell (also called band neutrophil, band form or stab cell) is a cell undergoing granulopoiesis, derived from a metamyelocyte, and leading to a mature granulocyte. It is characterized by having a curved but not lobular nucleus. [1] The term "band cell" implies a granulocytic lineage (e.g., neutrophils). [2]
Neutrophils may be subdivided into segmented neutrophils and banded neutrophils (or bands). They form part of the polymorphonuclear cells family (PMNs) together with basophils and eosinophils. [3] [4] [5] The name neutrophil derives from staining characteristics on hematoxylin and eosin histological or cytological preparations.
Absolute neutrophil count (ANC) is a measure of the number of neutrophil granulocytes [1] (also known as polymorphonuclear cells, PMN's, polys, granulocytes, segmented neutrophils or segs) present in the blood. Neutrophils are a type of white blood cell that fights against infection.
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.
Neutrophils, as primary effector cells of the innate immune defense, originate from HSCs through a series of differentiation stages. The emergency granulopoiesis significantly accelerates this differentiation process, ensuring a rapid replenishment of neutrophil populations in response to systemic inflammatory stimuli, thus maintaining immune ...
The standard definition of a left shift is an absolute band form count greater than 7700/microL. [3] There are competing explanations for the origin of the phrase "left shift," including the left-most button arrangement of early cell sorting machines [4] [5] and a 1920s publication by Josef Arneth, containing a graph in which immature neutrophils, with fewer segments, shifted the median left. [6]
The band got its name when Stills and bandmate Richie Furay stayed at a friend's house with a steamroller parked outside. The piece of heavy equipment bore the words "Buffalo Springfield Roller ...
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 ...
