It is indeed supported by a further observation of Jolly on the mononuclear eosinophil cells of the marrow.
It is especially important that the mononuclear and the leucocytes associated with them, undergo no increase.
In our cases the mononuclear cells have averaged 66 per cent., which is somewhat high even for infants.
The mononuclear and transitional forms of the neutrophil group, do not under normal circumstances pass over into the blood-stream.
In contradistinction to the polynuclear neutrophil elements, these mononuclear forms shew no amœboid movement on the warm stage.
Zappert expressly mentions that these mononuclear cells were in no way similar to the lymphocytes in general appearance.
We begin with the discussion of the mononuclear neutrophil cells, Ehrlich's "myelocytes."
The bone-marrow forms which are free from granules consist mostly of mononuclear cells of different type.
mononuclear mon·o·nu·cle·ar (mŏn'ō-nōō'klē-ər, -nyōō'-)
Having only one nucleus.
