Cell Centered Database

Web Link

The Cell Centered Database (CCDB) is a web accessible database for high resolution 2D, 3D and 4D data from light and electron microscopy, including correlated imaging.

George E. Palade EM Slide Collection

Web Link

The George Pallade collection includes early electron micrographs from Rockefeller University and Yale University. Many of the images are significant for their contribution to our understanding of cellular structure and processes. The images were used in the cell biology courses at Yale University by Drs. George Palade and Marilyn Farquhar. It was Dr. Palade's wish that the collection of images be freely available to students and scientists world-wide.

Web Link

The first electron microscope image of an intact cell at a magnification of 1600x. The image reveals mitochondria, the Golgi apparatus and a "lace-like reticulum" which was later named the "endoplasmic reticulum" by Keith Porter. The work was a collaboration between Albert Claude and Keith Porter from the Rockefeller Institute for Medical Research and Earnest Fullam of the Interchemical Corporation. the original publication is available in online.

Vocabulary of Microscopic Anatomy

Web Link

The vocabulary of microscopic anatomy includes explainations and images of over 250 microscopical anatomical terms. It is linked to a large collection of electron micrographs of cells and tissue. The images are only available for viewing online.

Microscope Development

From Intracellular Morphology to Function: The Secretory Pathway

Web Link

Working in Albert Claude research group at Rockefeller University, George Palade developed the sucrose method for cell fractionation which isolated organelles without distorting their shapes. By using osmium tetroxide better contrast was obtained in electron microscopy and Palade was able to describe the fine structure of mitochondria. This summary of Palade's work at Rockefeller University include a link references to journal articles.

Cell Fractionation, Biochemistry, and Electron Microscopy: The Birth of Modern Cell Biology

Web Link

Albert Claude pioneered techniques of cell fractionation and was the first to use an electron microscopes to study cells. This first image of an intact cell, a collaboration with Keith Portor and Ernest Fullam, was termed it the "birth certificate" of the field of cell biology by George Palade. This summary of his work at Rockefeller University includes links to selected publications.

Advances in high-resolution imaging – techniques for three-dimensional imaging of cellular structures

Web Link

This 2012 commentary provides an excellent overview of microscopic techniques used in the 3D imaging of cellular structures. Advances in electron microscopy tomography and fluorescence super-resolution techniques including STED, Single-molecule-localization-based super-resolution, Plane illumination microscopy, and Structured illumination microscopy are reviewed. There is an insightful comparison of super resolution techniques to confocal microscopy in terms of difficulty of preparation, processing and live cell.
