A study of tissue culture cells by electron microscopy: Methods and preliminary observations.

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.

George E. Palade EM Slide Collection

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.

Blackburn Gets Personal, Reflects on Path Leading Up to Nobel Prize

A week after being named UCSF’s—and her native Australia’s—first woman to receive a Nobel Prize in Physiology or Medicine, molecular biologist Elizabeth Blackburn, PhD, sat down with UCSF Chancellor Sue Desmond-Hellmann, MD, MPH, to discuss the elusive goal of work-life balance and the importance of following one’s passions and making time for “intense relaxation.”

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

ert 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.

From Intracellular Morphology to Function: The Secretory Pathway

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.

The Fly EM Project

Using electron microscopy the Fly EM project at Janelia Farm is developing technology to create a map of every neuron and synapse in the Drosophila nervous system. By establishing a map or fly ‘connectome’ that shows how all neurons in the fly brain are connected to each other, this will lead to a better understanding of brain function. Over 8,000 serial sections have been used to collect hundreds of thousands images. The project includes development of a semi-automated pipeline for serial section TEM reconstruction and exploring Scanning Electron Microscopy with Focused Ion Beam Milling (SEM-FIB) and Scanning Transmission Electron Microscopy (STEM) for improved data acquisition.
