The growth of individual seminal vesicle epithelial cells and their proliferation.

Histologically seminal vesicle epithelium (SVE) of the intact adult guinea pig is a discrete and segregated monolayer of highly specialized tall columnar cells. The epithelial layer is so sharply demarcated from its attached stroma (primarily smooth muscle), that blunt dissection alone is sufficient to separate epithelium from muscle. After castration the epithelial cells decrease in both size and number so that by the fifth day, the surviving cells are greatly involuted structurally and comprise only about 12% of the original numerical population normally present in one seminal vesicle.

Nuclear protein matrix of seminal vesicle epithelium.

Nuclear protein matrix was isolated from guinea pig seminal vesicle epithelium and liver. The two matrices were similar in fine structure as seen by transmission electron microscopy, in protein electropherograms, and in percent composition relative to protein, DNA, and RNA. Scanning electron microscopy was used to examine intact seminal vesicle nuclei, nuclei after treatment with Triton X-100 and DNAse I, and purified nuclear matrix.
