Reticulocyte - Reticulocyte

Japanese: 網赤血球 - もうせっけっきゅう（英語表記）reticulocyte

They are also called reticulocytes. When supravital staining is performed with brilliant Cressil blue or new methylene blue, a reticulated substance that stains blue can be seen. Such red blood cells are called reticulocytes. They are the youngest of red blood cells, and lose their reticulated substance within 2 to 3 days and become mature red blood cells. An increase in the number of reticulocytes during blood loss indicates active red blood cell production. In other words, the number of reticulocytes decreases in hemolytic anemia, in which red blood cell production is enhanced, and in aplastic anemia, in which red blood cell production is reduced and increases after acute bleeding.

網状赤血球ともいう。ブリリアントクレシール青あるいはニューメチレン青で超生体染色を行うと，青染する網状物質が認められる。このような赤血球を網赤血球という。赤血球のなかで最も若く，網赤血球は2～3日で網状物質を失い，成熟赤血球になる。流血中に網赤血球数が増加していることは，赤血球の生成が盛んであることを示す。つまり，赤血球の生産が亢進する溶血性貧血，急性出血後にふえ，赤血球の生産が低下する再生不良性貧血などで減少する。
