re·tic·u·lo·cyte R0192600 (rĭ-tĭk′yə-lō-sīt′)n. An immature red blood cell that (in mammals) lacks a nucleus but contains a network of filaments consisting of residual RNA and organelles. Reticulocytes move from the bone marrow into the bloodstream.

re·tic′u·lo·cyt′ic (-sĭt′ĭk) adj.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.
