reticulocyte

reticulocyte
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. SEE ALSO: erythroblast. SYN: reticulated corpuscle, skein cell. [reticulo- + G. kytos, cell]

n.
an immature red blood cell (erythrocyte). Reticulocytes may be detected and counted by staining living red cells with certain basic dyes that result in the formation of a blue precipitate (reticulum) within the reticulocytes. They normally comprise about 1% of the total red cells and are increased (reticulocytosis) whenever the rate of red cell production increases.

re·tic·u·lo·cyte (rə-tikґu-lo-sīt″) [reticulo- + -cyte] an immature erythrocyte showing a basophilic reticulum under vital staining.
