Title: Polychromatic erythroblasts (bone marrow, rabbit)
Description: Electron microscopy.
Shown are two polychromatic erythroblasts (1) or intermediate normoblasts between other erythroblasts and reticulocytes (2). Few mitochondria and polysomes are present but there is a decrease in amount of all organelles and nuclear clumping starts to take place. During this maturing stage in the development the hemoglobin synthesis commences and the cytoplasm becomes more electron-dense.
