## Abstract The surfaces of cells from the early embryo of the chick were examined using electron microscope techniques for the visualization of concanavalin Aโbinding sites. Horseradish peroxidase and Ferritin labelled concanavalin A were used to determine the distribution of the binding sites. Al
The rate of 3H-thymidine incorporation and of cell proliferation in chick embryo fibroblast cultures are reduced coordinately when the [Mg2+] of the external medium is reduced below the physiological concentration of about 0.8 mM. These effects of moderately reduced [Mg2+] and the accompanying chang
## Abstract Treatment of chick embryo fibroblasts with 0.5% Tritonยฎ Xโ100 extracts most of the cell protein, leaving an organized part of the cell structure attached to the tissue culture dish. This โTriton cytoskeletonโ consists largely of intermediateโsized filaments and bundles of microfilaments
