SUMMARY
Normal and stimulated peritoneal cells have been examined with the Stereo-scan scanning electron microscope. Normal lymphocytes were identified by their small size; some had numerous small stubby or pointed processes on their surfaces. Macrophages were larger and had ridge-like processes. Many of the stimulated cells showed no significant deviation from normal. Others, all macrophages, showed a marked deviation from the normal spherical shape. Ridge-like processes were more prominent on their surfaces, and large flange-like processes and a few finger-like processes were seen. This suggests that on stimulation peritoneal cells become more deformable and therefore irregular in shape, and that their surfaces become rougher.read more

Metal toxicity for rabbit alveolar macrophages in vitro
TL;DR: Using scanning electron microscopy it was possible to correlate surface alterations with exposure concentrations and cell viabilities so as to suggest a mode and sequence of cell injury which may ultimately lead to cell death.

The morphology of the polysaccharide coat of mammalian cells.
TL;DR: The electron microscope problem of how attempts can be made to directly resolve individual molecular assemblies of the carbohydrate components is discussed with respect to preserving the surface coat in its natural wet state, obtaining adequate contrast and resolution, and minimizing electron beam radiation damage.

Supraependymal cells of hypothalamic third ventricle: identification as resident phagocytes of the brain
TL;DR: The importance of ependyma and ventricular phagocytes as a first line of defense against viral invasion of the brain, as well as their role in the pathogenesis of certain virus-related diseases, is suggested by a number of experimental and clinical observations.

'Hairy' cell leukaemia (leukaemic reticuloendotheliosis): a scanning electron microscopic study of eight cases.
TL;DR: From the examination of these cases, it is evident that scanning electron microscopy may be used as a means of distinguishing chronic lymphocytic leukaemia from ‘hairy’ cellLeukaemia on the basis of surface ultrastructure.

TL;DR: From data, it appears that the conversion of a monocyte-like cell to a mature macrophage is accompanied by the formation of increased numbers of lysosome-like cytoplasmic organelles.

TL;DR: A simple method for the preparation of ciliated epithelia for study with the scanning electron microscope is described and ciliary groups are well preserved and it is possible to discern individual cilia and work out their numbers and orientation.

TL;DR: The surfaces of the epithelium and the endothelium of the cornea were studied with the Stereoscan and with the conventional electron microscope to find out why scale-like lipid particles seem to come off from this layer.

TL;DR: A new method for examining the surface of blood cells, using the Stereoscan electron microscope, is described, and some of the cellular appearances revealed by this technique are illustrated.

The fine structure of the cells of the mouse peritoneum.
TL;DR: The cells of the peritoneum of the mouse have been examined with the electron microscope both by studying the gastro-splenic omentum and by washing the cells out of theperitoneal cavity, finding a gradation of structure was seen between lymphocytes and small macrophages.
