WebApr 10, 2024 · Background: Sickle cell disease (SCD) is a highly prevalent genetic disease caused by a point mutation in the HBB gene, which can lead to chronic hemolytic anemia and vaso-occlusive events. Patient-derived induced pluripotent stem cells (iPSCs) hold promise for the development of novel predictive methods for screening drugs with anti … As they mature, a number of erythrocyte characteristics change: • The overall size of the erythroid precursor cell decreases, increasing the cytoplasmic to nucleus (C:N) ratio. The nuclear diameter decreases and chromatin condenses with the staining reaction progressing from purplish red to dark blue at the final nuclear stage of the orthochromatic erythroblast, prior to nuclear ejection.
