Electron Microscope Observations on Intracellular

Relatively few malignant neoplasms have been described in amphibia. The one that has been studied most extensively is the Luck6 renal adenocarcinoma of the frog, Rana pipiens. This malignant tumor occurs in from two to four per cent of frogs of this species, collected in the Lake Champlain region of northern Vermont and adjoining areas of Quebec. In a series of papers Luck6 described its histop...

Isotope analysis in the transmission electron microscope

The Ångström-sized probe of the scanning transmission electron microscope can visualize and collect spectra from single atoms. This can unambiguously resolve the chemical structure of materials, but not their isotopic composition. Here we differentiate between two isotopes of the same element by quantifying how likely the energetic imaging electrons are to eject atoms. First, we measure the dis...

Electron microscopy’s multi-tool: the Scanning Transmission Electron Microscope

A dedicated Scanning Transmission Electron Microscope is ideally coupled with the energy dispersive x-ray and electron energy loss spectroscopies to obtain information about the chemical composition, morphology and electronic structure on the nanoscale. With several signals being available simultaneously with the pass of a subnanometre-sized beam, this instrument can answer questions from a bro...

Electron Microscope Observations on Frozen-dried Cells

To explore the problem of artefacts which may be produced during usual fixation, dehydration, and embedding, the authors have examined pancreas, liver, and bone marrow frozen at about -180 degrees C., dried, at -55 to -60 degrees C., embedded in methacrylate, sectioned, and floated on a formol-alcohol mixture. By these treatments the labile structure of living cells can be fixed promptly and em...

Electron microscope observations on mitotic chromosomes.

A method is described by which single mitotic cells growing in tissue culture can be selected under the light microscope and then sectioned for electron-microscopic study. The method has been applied to mitotic cells in newt heart cultures and to monolayer cultures of human fibroblasts. The structure of the chromosomes and of the mitotic apparatus at various phases of mitosis are described and ...
