STUDIES IN ELECTRON MICROSCOPY OF BLOOD CELLS
M. BESSIS M.D.1

The study of blood cells with the electron microscope necessitates special
methods which as yet are not completely precise. The methods of smearing on
Formvar, of destruction by pressing on a wet smear, and of shadow casting are
those which have been used most frequently.
The author reviews the electron microscopy of thrombocytes, granulocytes and
erythrocytes and discusses the ultrastructure of the hyaloplasm. Azurophilic,
neutrophilic and eosinophilic granules can be very well observed with the electron
microscope. Chronic and acute luekemic cells exhibit certain granules and paracrystals, the significance and specificity of which are not yet clearly established.
