The Endoplasmic Reticulum
Original Findings on Cultured MateriaL--The relatively short history of the endoplasmic reticulum started 10 years ago, in 1945, when Porter, Claude, and Fullam (1), noted the presence of a "lace-like" reticulum in the ground substance of ceils grown in tissue culture and examined in toto in the electron microscope. In describing their findings, these authors mentioned that "at higher magnifica...
متن کاملThe Plant Endoplasmic Reticulum - ReadingSample
The endoplasmic reticulum (ER) is a non-uniform compartment in plants as regards its morphology and function. It extends as a highly anastomosing membranous network throughout the cytoplasm, is the major compartment of membrane biogenesis, and has been verified to function as the starting site for the secretory pathway. Early electron microscopy studies revealed three morphological ER sub-domai...
متن کاملDiffusion in the Endoplasmic Reticulum
Diffusion processes in the lumen of the endoplasmic reticulum of tissue derived cells are investigated using a computational approach based on the method of particle strength exchange. 3D reconstructions of the shape of the endoplasmic reticulum are made from micrograph sections and are then used to conduct direct numerical simulations of fluorescence recovery experiments. The influences of the...
متن کاملConstruction of the endoplasmic reticulum
To study the construction of the ER, we used the microtubule-disrupting drug nocodazole to induce the complete breakdown of ER structure in living cells followed by recovery in drug-free medium, which regenerates the ER network within 15 min. Using the fluorescent dye 3,3'-dihexyloxacarbocyanine iodide to visualize the ER, we have directly observed the network construction process in living cel...
متن کاملNetworking in the endoplasmic reticulum.
The network of the ER (endoplasmic reticulum) is set up by cytoskeletal control of the movement and remodelling of polygonal rings of tubules, bundles of tubules and cisternal regions. We have developed a new image analysis tool, persistency mapping, to understand the framework upon which the plant ER remodels. With this new tool, we have explored the network nodes, called anchor/growth sites, ...
