the results demonstrate that ( 1 ) the volume density of mitochondria in the cytoplasm decreases by 34 % during maturation from ( en- ) - to ( en + ) -erythroblasts ( p less than 0.001 ) and by 60 % during differentiation from ( en + ) -erythroblasts to reticulocytes ( p less than 0.001 ) , ( 2 ) a fivefold increase in the volume density of autophagosomes in the cytoplasm is noted during maturation from ( en- ) - to ( en + ) -erythroblasts ( p less than 0.01 ) , whereas the value of this parameter remains essentially unchanged during the subsequent differentiation to reticulocytes , ( 3 ) no mitochondria are found inside autophagosomes of ( en- ) -erythroblasts , whereas mitochondria occupy 26 % and 35 % , respectively , of the autophagosomal volume in ( en + ) -erythroblasts and in reticulocytes .
