reticulocyte

 [rĕ-tik´u-lo-sīt″]
a young erythrocyte showing a basophilic reticulum under vital staining.

re·tic·u·lo·cyte

(re-tik'yū-lō-sīt'),
A young red blood cell containing a basophilic cytoplasmic network precipitated by brilliant cresyl blue representing residual polyribosomes; such cells become more numerous during the process of active blood regeneration.

/re·tic·u·lo·cyte/ (rĕ-tik´u-lo-sīt) a young erythrocyte showing a basophilic reticulum under vital staining.

reticulocyte

(rĭ-tĭk′yə-lō-sīt′)
n.
An immature red blood cell that contains a network of basophilic filaments.

reticulocyte

[ritik′yələsīt′]
Etymology: L, reticulum + Gk, kytos, cell
an immature erythrocyte characterized by a meshlike pattern of nucleic acids when stained using new methylene blue dye. Reticulocytes normally account for less than 2% of the circulating erythrocytes. A greater proportion reflects increased bone marrow generation of red blood cells. Compare erythrocyte. See also normoblast. Also called polychromatophilic erythrocyte when seen in a Wright-stained peripheral blood film.

re·tic·u·lo·cyte

(rĕ-tik'yū-lō-sīt)
A young erythrocyte that contains no nucleus but has residual RNA. The RNA can be visualized as granules or filaments when the cell is stained supravitally with new methylene blue. Normally, new red cells are released from the bone marrow to the peripheral blood as reticulocytes. They mature, losing the filamentous RNA in about 2 days. Reticulocytes comprise about 1% of circulating red blood cells. Increased concentrations are associated with hemolytic anemia and blood loss. Decreased concentrations are associated with ineffective erythropoiesis, aplastic anemia, and hypocellularity of erythroid precursors in the bone marrow.

reticulocyte

An immature red blood cell (ERYTHROCYTE) that contains a network that can be stained blue with basic dyes. Reticulocytes appear in the circulation at times of increased red cell formation.

Reticulocyte

An early, immature form of a red blood cell. Over time, the reticulocyte develops to become a mature, oxygen-carrying red blood cell.

n an immature erythrocyte. Reticulocytes normally account for less than 2% of the circulating erythrocytes.

reticulocyte

a stage of erythrocyte maturation, between normoblast (metarubricyte) and mature erythrocyte, showing a basophilic reticulum (residual RNA) under vital staining.

corrected reticulocyte percentage (CRP)
percentage reticulocytes ÷ (hematocrit ÷ normal hematocrit); a measure of reticulocyte numbers adjusted for the degree of anemia.
reticulocyte count
performed on blood mixed with a supravital stain such as new methylene blue or brilliant cresyl blue. An increased count indicates active erythropoiesis.
reticulocyte production index (RPI)
corrects the reticulocyte count, taking into account the presence of anemia and the presence of shift reticulocytes producing a more accurate indicator of red cell production.
reticulocyte response
the release of reticulocytes in response to erythropoietin or administration of specific therapy for anemia, e.g. a deficiency of iron or folic acid. A reticulocyte response does not develop until the anemia is marked in cattle and not at all in horses.
shift reticulocyte, stimulated reticulocyte
with intense stimulation of erythropoiesis there is premature release of reticulocytes from the bone marrow into peripheral blood. These are larger and contain more reticulum than normal reticulocytes.
