The fine structure of epithelial cells of the small ventral prostate of Pseudomys australis males was studied. The cells were sometimes binucleated, exhibited relatively little granular endoplasmic reticulum, generally few secretory granules (probably reflecting a low proteinaceous secretory activity), but had abundant agranular endoplasmic reticulum (AER), similar to that in steroidogenic cells. Some of the mitochondria also showed tubular cristae. Furthermore, most cells had some irregular dense bodies in the cytoplasm which may have developed, by a gradual transformation process, from the membranes of AER, mitochondria and other organelles; they could be the product of degenerative changes in these organelles. These findings indicate a significant difference in the structure of these cells from those present in the ventral prostate of the hopping mouse, Notomys alexis. It is speculated that this gland secretes relatively little protein but perhaps more lipid or cholesterol-derived substance.
对南方伪鼠雄性小鼠腹侧前列腺上皮细胞的精细结构进行了研究。这些细胞有时双核，粗面内质网相对较少，通常分泌颗粒也很少（可能反映出蛋白质分泌活性较低），但有丰富的滑面内质网（AER），类似于类固醇生成细胞中的滑面内质网。一些线粒体也显示出管状嵴。此外，大多数细胞的细胞质中有一些不规则的致密体，它们可能是通过一个逐渐转变的过程从AER、线粒体和其他细胞器的膜发展而来的；它们可能是这些细胞器退行性变化的产物。这些发现表明这些细胞的结构与跳鼠Notomys alexis腹侧前列腺中的细胞有显著差异。据推测，该腺体分泌的蛋白质相对较少，但可能分泌更多的脂质或胆固醇衍生物质。
