Pro erythroblast is the first cell which is responsible for the formation of many red blood cells because when these cells formed ,divide several times and form many mature red blood cells.
The 1st generated cells are called besophil erythroblast because they can be stained with basic dyes. The at this time the cell has very little hemoglobin. However in succeeding generation the cell becomes filled approx 33% hemoglobin. At the same time the endoplasmic reticulum is reabsorbed. The cell at this steps is called reticul: eytes.
The remaining bchophilic materiel in reticnlocyte disappear with in 1--2 days and the cell is then converted into mature erythrocytes.
