Electron microscopic analysis of the structure of metaphase chromosomes after liposome treatment

: The fine structure of the methaphase chromosomes from the Chinese hamster cell culture was studied after the incubation with lyposomes isolated from hen egg yolk phosphatidilcholine, or from the total rat liver phospholipid. It has been found that during incubation lyposomes surround chromosomes, form a multifold covering considerably decondensing the chromosome matrix. The data obtained indicate that the analogues of cell membrane - lyposomes - may be involved in the regulation of the structural organization of metaphase chromosomes.
