The size and number of fibrillar centers (FCs) was shown to be proportional to or correlate with the ploidy of the cell, respectively. In the active nucleoli of erythroblasts, the numbers of FCs exceeds several-fold that of nucleoli organizing regions (NORs). In the course of maturation, the number of FCs becomes 3-10 times lower than that of NORs. The… CONTINUE READING
