Erythropoiesis (C0014819) |
|
|---|---|
| Definition (GO) | The process in which a myeloid precursor cell acquires specializes features of an erythrocyte. [GOC:mah] |
| Definition (NCI) | A biological process that refers to the maturation of erythrocytes. |
| Definition (NCI) | A hematopoietic process that refers to the production of erythrocytes. |
| Definition (CSP) | production of red blood cells. |
| Definition (MSH) | The production of red blood cells (ERYTHROCYTES). In humans, erythrocytes are produced by the YOLK SAC in the first trimester; by the liver in the second trimester; by the BONE MARROW in the third trimester and after birth. In normal individuals, the erythrocyte count in the peripheral blood remains relatively constant implying a balance between the rate of erythrocyte production and rate of destruction. |

Reticulocytes (C0035286) |
|
|---|---|
| Definition (MSHCZE) | Předposlední, již bezjaderné vývojové stadium červené krvinky, po němž už následuje zralý erytrocyt. Vzniká z erytroblastu vypuzením buněčného jádra v kostní dřeni a za několik dnů dozrává v periferní krvi. Obsahuje zbytky organel. Množství r. v periferní krvi (vyjádřeno relativně v procentech všech červených krvinek, norm. cca 1 %) odráží erytropoetickou aktivitu dřeně. Je zvýšeno při její aktivaci (viz retikulocytóza) a sníženo při dřeňových útlumech. (cit. Velký lékařský slovník online, 2013 http://lekarske.slovniky.cz/ ) |
| Definition (NCI) | Immature erythrocytes that have just undergone extrusion of their cell nucleus. They still contain some organelles that gradually decrease in number as the cells mature. |
| Definition (MSH) | Immature ERYTHROCYTES. In humans, these are ERYTHROID CELLS that have just undergone extrusion of their CELL NUCLEUS. They still contain some organelles that gradually decrease in number as the cells mature. RIBOSOMES are last to disappear. Certain staining techniques cause components of the ribosomes to precipitate into characteristic "reticulum" (not the same as the ENDOPLASMIC RETICULUM), hence the name reticulocytes. |
| Definition (CSP) | immature erythrocytes showing a basophilic reticulum under vital staining; in humans, these are erythroid cells that have just undergone extrusion of their cell nucleus. |
