The early developmental stages are immature cells that give rise to mature corpuscles that are released into the general circulation. Early developmental stages in the image include cells that give rise to: neutrophils, eosinophils (very distinct granules), monocytes and erythrocytes (red blood cells). The younger neutrophils are called bands and their nucleus is C-shaped. Erythroblasts and normoblasts are immature red blood cells.
