Ultrastructural study of nuclear pores in hypertrophied heart cells.
Nuclear pores were consistently found in both spontaneous and experimentally induced hypertrophy. The structure of nuclear pores in hypertrophied hamster, guinea pig, and rabbit heart cells was similar. The morphology of nuclear pores was similar to that previously seen in normal cardiac cells and in other cell types. Each pore complex was composed of a pore sometimes containing a central granule, a pore margin having an octagonal shape, and two rings of annular granules lying upon the pore margin.
