Polyglucose particles artificially synthesized under histochemical conditions from glucose 1-phosphate by phosphorylase and branching glycosyltransferase in the nuclei of skeletal muscle fibers, satellite cells and endothelial cells of the blood capillary of the normal rat were studied at the electronmicroscopic level. Newly formed polyglucose particles appeared in the karyolymph and interchromatin area of nuclei as a large macromolecular structure of spheroidal branching bodies. The size of
