The ultrastructure of synchronized hela cells
Journal of Cell Science, 1971ABSTRACT Synchronous populations of mitotic HeLa cells were obtained by the controlled agitation method, and a detailed morphological study of the cells in all phases of the cell cycle was under-taken to correlate variations in cell structures to known coexisting biochemical events. Auto-radiographic techniques using tritiated thymidine (

Subribosomal particles of HeLa cells
Experimental Cell Research, 1974Abstract Well defined ring-shaped and rectangular particles are described as intracellular components of post-ribosomal cytosol of HeLa cells. Their morphology might be identical with particles recently isolated from plasma cell tumors and independently from the culture medium of malignant cells.

Multiplication of Solitary HeLa Cells
Nature, 1958THERE are many occasions when it is desirable to grow animal cells from solitary inocula (for example, in order to obtain clones); for this reason, it seems worthwhile to record the following conditions which allow multiplication of isolated HeLa cells.

Abstract 1. 1. A simple procedure to obtain DNA-free RNA polymerase (nucleosidetriphosphate: RNA nucleotidyltransferase, EC 2.7.7.6) from HeLa cells was developed from the preparation of extracts in a hypotonic medium in a French pressure cell. 2. 2.

Mitochondrial Ribosomes in HeLa Cells
Nature New Biology, 1971HeLa cell mitochondria contain 60S ribosomes which seem to consist of subunits of 45S and 35S particles. The 16S and 12S RNA components are coded by mitochondrial DNA.

Upconversion fluorescent nanoparticles can convert a longer wavelength radiation (e.g., near-infrared light) into a shorter wavelength fluorescence (e.g., visible light) and thus have emerged as a new class of fluorescent probes for biomedical imaging ...

Publisher Summary HeLa cells are not so fastidious concerning medium, and many kinds of media with different components have been used for the genetic study of HeLa cells. HeLa cells grow in a defined medium, such as Ham's F12 medium supplemented with insulin, transferrin, hydrocortisone (aldosterone), fibroblast growth factor, and epidermal growth ...

Endo- and exocytosis of zwitterionic quantum dot nanoparticles by live HeLa cells.
ACS Nano, 2010Uptake and intracellular transport of D-penicillamine coated quantum dots (DPA-QDs) of 4 nm radius by live HeLa cells have been investigated systematically by spinning disk and 4Pi confocal microscopies.

Archiv f�r die gesamte Virusforschung, 1965
A strain of varicella virus was isolated and easily maintained in HeLa cells. The infection could be passed with live cells only, practically all infectivity being destroyed by disruption of the cells with sonication or repeated freeze-thawing, even if precautions were taken to favour the infectivity of nucleic acids.

Chemical Toxicity on HeLa Cells
Current Medicinal Chemistry, 2006HeLa cells were named for Henrietta Lacks, who died in 1952 from an infection of a special type of cancer. Margaret Gey, her physician, started working with these cancer cells that are still used for medical research. In the present review, an attempt has been made to collect the data for the effects of different chemicals on HeLa cells and to discuss ...
