Document Summary

Chromatin has started to condense: polychromatophilic erythroblast. Pink (eosinophilic) patches in cytoplasm due to collection of haemoglobin. Still has basophilic staining because of ribosomes. This is the last stage at which division occurs: normoblast. Does not divide!! (because of condensed nucleus: reticulocyte. Forms upon the extrusion of the nucleus. Some ribosomes are present, therefore, can have a slight blue tinge: erythrocyte. Erythropoietin (epo) stimulates erythrocyte production near the committed stem cell stage. It is produced by the kidneys in response to low o2 levels: an increase in the number of rbcs in the bloodstream means more o2 can be carried. Blood doping refers to the process where you take out your own blood/someone else"s blood and store it: you then add it back before competition to increase rbc count to carry more o2. Low iron results in small, pale cells (due to lack of haemoglobin)
