Medical visualization taken from human scanned data showing a polychromatophilic erythroblast, which is one of the stages in the process of erythropoiesis (red blood cell production). A polychromatophilic erythroblast houses a large nucleus that stains both purple and pink because of the presence of ribosomes and haemoglobin. The nucleus also appears clumped because of thick chromatin strands. In the process of erythropoiesis, the original stem cell transforms into a committed cell (proerythroblast), and then moves on to phase 1 of the developmental pathway as a basophilic erythroblast. Erythropoietin, a hormone that is produced by the kidneys, binds to the cell to make the late erythroblast (polychromatophilic erythroblast), which begins phase 2 of the developmental pathway. From here the cell develops into a orthochromatophilic normoblast, then reticulocyte, and finally an erythrocyte. | |
