The secretory granule and the lysosome in the epithelium of the seminal vesicle

Abstract

It is the purpose of this paper to point out the differences between the secretory granules and the lysosome-like granules occurring in the epithelium of the naked mouse seminal vesicle. In spite of an extensive literature servey, sufficient information of the difference between them could not be obtained. A few studies have been done since Fellinger and Pakeschl) reported about electron microscopic investigations of the seminal vesicle. In recent papers, Deane, H. W., Wurzelmann, S., Porter, K. R., Takemoto, K. and Fujita, M. reported about the fine structure of the epithelium of the seminal vesicle. However, they stated little about the difference between the secretory granules and the lysosome-like granules. The purpose of this paper is to investigate electron microscopically the difference in more detail.
