B: Mitochondrial swelling and degranulation of rough endoplasmic reticulum
in the prostate cells from the dogs in the G3 group (arrow, x10000).
The rough endoplasmic reticulum
was well developed and showed an organized pattern.
The nuclei of the cells of the epithelium, containing considerable amounts of rough endoplasmic reticulum
, are irregularly shaped.
With cytoplasmic growth, a number of mitochondria and the rough endoplasmic reticulum were concentrated around the perinuclear region in the cytoplasm.
At the same stage, lipid droplets that were surrounded by the mitochondria and well-developed rough endoplasmic reticulum appeared near the cortical granules and exogenous substances.
Virus particles formed upon membranes of the "budding compartment," a term used to describe the continuous membrane system from the rough endoplasmic reticulum
to the Golgi complex (23,24).
The cytoplasm contains numerous free ribosomes, large mitochondria, many vesicles and vacuoles containing electron-dense material; but the rough endoplasmic reticulum
and Golgi complexes are sparse (Figs.
Rough endoplasmic reticulum
is scarce, but the cytoplasm is rich in mitochondria and disperse glycogen granules.
Additional features of the tumor cells included moderately abundant mitochondria, stacks of rough endoplasmic reticulum
, and polyribosomes.
The tumor cell cytoplasm contained scattered mitochondria, profiles of rough endoplasmic reticulum
, Golgi's apparatus, and a few nonspecific intermediate filaments and particulate glycogen (figure 4).
The cytoplasm contained moderate amounts of mitochondria, rough endoplasmic reticulum
, electron-dense granules of variable sizes, most likely representing lysosomes, and thin filaments (Figure 4).
The spindle cell population consisted of bipolar cells with large oval nuclei that contained macronucleoli and scattered rough endoplasmic reticulum
, mitochondria, and lysosomes within their cytoplasm.
