Eosinophilic myelocytes

Eosinophilic myelocytes are the first definitive cell type in the eosinophilic lineage. At this stage, the cells begin to synthesize eosinophil-specific granules, which then come to predominate since azurophilic granules are no longer being produced. The nucleus of an eosinophilic myelocyte will develop a distinct indentation, at which point they become metamyelocytes. 1000x, 1000x

Specific or secondary granules in eosinophils contain a variety of proteins including eosinophil major basic protein, RNAases and peroxidase; enzymes important for combating multicellular parasites and certain infections. Due to the cationic nature of these contents, the granules stain intensely with eosin.
