Morphological characteristics of promyelocytes. So, promyelocytes, the cytoplasm will be basophilic. It'll be blue, and they'll be primary azurophilic granules. So, this is the pink granule. These granules are, uh, maybe on top of the nucleus, obscuring the nucleus, which is a unique thing to, uh, to see in the granulocyte lineage.
And, um, the nucleus of the promyelocyte will be less mature, or should say more mature than a blast. Nucleoli and some slight heterochromatin.
