Electron Microscopic Studies on Primary Culture Cells from Human Oral Tissues

Electron Microscopic Studies on Streptococci

The location of Group A carbohydrate in the streptococcal cell wall has been studied by several ultrastructural techniques. The findings, based largely on use of ferritin- and horseradish peroxidase-conjugated antibodies, are interpreted as demonstrating a discrete laminar distribution of the group-specific polysaccharide. This carbohydrate layer is located on the outermost surface of the cell ...

Electron Microscopic Studies of the Follicle Cells

The thyroid gland holds a unique situation among the endocrine glands. The follicle cells line the follicle cavity by their apical surface and have an intimate relation with the capillaries at their basal surface. Until recently, attention has been paid to the problem of function involved in this arrangement by light microscopy. Hormone substance secreted into the follicle cavity and stored her...

Electron microscopic studies on dog testicular interstitial cells.

The ultrastructure of the dog testicular interstitial cells is described. The cells are characterized by numerous tubules of agranular endoplasmic reticulum, many large lipid droplets, different types of dense bodies including heterogeneously dense bodies, giant mitochondria containing lipid droplets, a few microtubules, and well-developed cytoplasmic filaments and their specific organization. ...

Electron Microscopic Studies on a Human Fibromyxosarcoma 1

Electron microscopic observations of tumor tissue classified as fibromyxosarcoma revealed the presence of 2 morphologically de finable cell types: a dense fibroblast-like cell and a pale cell. Infrequently, cells with features common to both the dense and pale cells were observed. Both cells types contained numerous filaments, dilated cisternae, and large vacuoles with apparent degenerative cel...
