Abstract
White blood cells have been studied in the back-scattered electron imaging (BEI) mode of scanning electron microscopy (SEM) with cytochemical methods for endogenous peroxidase, acid phosphatase, and a silver-staining method for nuclei. Peroxidase-positive granules were seen with good contrast and resolution in myeloid precursor cells and acid phosphatase activity was easily detected in macrophages and monoblasts. Silver staining permitted recognition of the shapes and location of the nuclei. In spite of the cytochemical procedures, cell surface structures were reasonably well-preserved in all methods, making direct correlation of BEI and secondary electron imaging (SEI) images an attractive feature in cell research with the scanning electron microscope.
