What is the N:C ratio of a prorubricyte?

As erythroid cells mature, the nucleus becomes smaller relative to the cytoplasm, so the N:C ratio falls. At the prorubricyte stage (the basophilic normoblast), the nucleus is still relatively large but the cytoplasm is increasing as RNA drives hemoglobin synthesis. This places the N:C ratio around 6:1. Earlier stages have a higher ratio (8:1 in the rubriblast), and later stages show a lower ratio (about 4:1 in rubricyte and ~2:1 in metarubricyte). The prorubricyte’s basophilic cytoplasm reflects its high RNA content during active hemoglobin production, matching a 6:1 ratio.
