Abstract The location of Russell bodies in the human plasma cell was shown by electron microscopy to be within the intracisternal space of the endoplasmic reticulum. The significance of this finding was discussed from the standpoint of possible intracellular function of the endoplasmic reticulum. The appearance of the affected plasma cells tended to negate a degenerative process, and the suggestion was offered that the Russell body results from a condensation of intracisternal secretion.

C3h Mice

An electron microscope study was made of a series of transplanted MPC-1 plasma-cell tumors carried by BALB/c mice. Large numbers of particles similar in morphology to virus particles were present inside the endoplasmic reticulum of tumor plasma cells. Very few particles were seen outside the cells or in ultracentrifuged preparations of the plasma or ascites fluid. In very early tumors particles were occasionally seen free in the cytoplasm adjacent to finely granular material. In general, the distribution of these particles inside endoplasmic reticulum is similar in early and late tumors. A few transplanted X5563 tumors of C3H mice were also examined. Large numbers of particles were found in the region of the Golgi apparatus in late X5663 tumors. A newly described cytoplasmic structure of plasma cells, here called a "granular body," appears to be associated with the formation of the particles. Particles present in MPC-1 tumors are exclusively of a doughnut form, whereas some of those in the inclusions of the late X5563 tumors show a dense center. Normal plasma cells, produced by inoculation of a modified Freund adjuvant into BALB/c mice. have been compared morphologically with tumor plasma cells of both tumor lines.

Electron Microscopic Localization

A new cytochemical method is presented for the light and electron microscopic localization of lysosomes in mineralized and soft tissues. Inorganic trimetaphosphate is used as substrate in a lead chelate incubation medium at pH 3.9. Lysosomes in several tissues are strongly reactive, and reaction product is frequently present in Golgi saccules and GERL. The reaction can be differentiated from acid glycerophosphatase activity, is relatively insensitive to fixation and demineralization procedures, and the reaction is often complete after short incubation times.

Electron Microscopic Localization

Although several electron microscopic studies of chordoma have been published, the origin of the chondroitin sulfate rich extracellular matrix is still not clear. Based on the ultrastructural similarities between the extracellular matrix, contents of the rough endoplasmic reticulum and cytoplasmic vacuoles, some authors assume that the two latter structures of chordoma cells contain mucosubstance. The intent of this study is to localize the sulfated glycosaminoglycans intracellularly in a chordoma, which provides cytochemical evidence of the origin of extracellular matrix.A sacrococcygeal chordoma from a 65 year old man was examined by electron microscopy after fixation in 2.5% gluta-raldehyde, 0.2% ruthenium red-glutaraldehyde, and pre-embedment staining with high iron diamine (HID), a method specific for sulfated glycoconjugates. Routine electron microscopic examination revealed stellate nonvacuolated and vacuolated “physaliferous” cells embedded in an abundant extracellular matrix. In general the chordoma cells possessed prominent Golgi complex, rough endoplasmic reticulum, mitochondria, glycogen and intermediate filaments.

The bis-(thioacetoxy) aurate (I) histochemical method has been refined to permit reliable electron microscopic localization of acetylcholinesterase and nonspecific cholinesterase in autonomic ganglia and other mammalian and submammalian tissues. The detailed procedure is presented, along with illustrations of its specificity by light microscopy and high degree of resolution by electron microscopy.

Lymph node cells of rabbits injected with sheep erythrocytes, identified as antibody-producing by their ability to produce plaques of hemolysis in erythrocyte-containing agar layers, have been examined by electron microscopy, by the use of a procedure devised for subjecting single cells to such examination. The antibody-producing cells thus examined were found to fall into two classes, according to the current terminology: some were in the category of lymphocytes, and others, in the category of plasma cells. Within each class, cells were found to vary in certain characteristics, especially in the degree of development of such organelles as the nucleolus, Golgi apparatus, and the endoplasmic reticulum. In the case of the endoplasmic reticulum especially, it could be seen that a series of these plaque-producing cells, ranked in order of increasing size and development of the endoplasmic reticulum, would extend over a considerable range from those lymphocytes with the least developed organelles to the mature plasma cells with the greatest development of these structures.

Electron Microscopic Localization

Specific contrast is conferred to subcellular antigen by applying purified antibodies, exhaustively labeled with uranium under immunospecific protection, to ultrathin sections. Use of Seligman’s principle of bridging osmium to metal via thiocarbohydrazide (TCH) intensifies specific contrast. Ultrathin sections of osmium-fixed materials were stained on the grid by application of 1) thiosemicarbazide (TSC), 2) unlabeled specific antiserum, 3) uranium-labeled anti-antibody and 4) TCH followed by reosmication. Antigens to be localized consisted of vaccinia antigen in infected HeLa cells, lysozyme in monocytes of patients with monocytic or monomyelocytic leukemia, and fibrinogen in the platelets of these leukemic patients. Control sections were stained with non-specific antiserum (E. coli).In the vaccinia-HeLa system, antigen was localized from 1 to 3 hours following infection, and was confined to degrading virus, the inner walls of numerous organelles, and other structures in cytoplasmic foci. Surrounding architecture and cellular mitochondria were unstained. 8 to 14 hours after infection, antigen was localized on the outer walls of the viral progeny, on cytoplasmic membranes, and free in the cytoplasm. Staining of endoplasmic reticulum was intense and focal early, and weak and diffuse late in infection.
