Ultrastructural and histochemical studies on human
gastric cancer
cells disclosed the presence of native and synthesized glycogen particles. The glycogen particles were investigated in the histochemical synthesis of glycogen particles from glucose 1-phosphate by the phosphorylase-
branching glycosyltransferase
system and non-incubated native glycogen in human gastric adenocarcinoma tubulare. It was observed that focal synthesis localized inthe intracytoplasmic matrix and intranucleus. Intranuclear synthesized glycogen appeared as a rosette form ranging from 1100 to 1300 A in diameter and free particles ranging from 325 to 900 A in diagmeter. The synthesis of glycogen appeared in the nucleus as well as in the cytoplasm of the human
gastric cancer
cells, and the synthesized glycogen was observed as a group of particles. Newly formed glycogen particles appeared occasionally in the interchromatin area as a large macromolecular structure of rosette form. Native glycogen appeared as a free-particle (250-333 A, medium =300 A) and aggregated rosette from (694-1050 A, medium=917 A) in the autophagosome of
gastric cancer
cells. There was not, however, a native glycogen particle in the nuclei of
gastric cancer
cells. Under certain conditons the nuclei of
gastric cancer
cells can acquire the capacity to synthesize glycogen.
