Leydig Cell Electron Micrograph
Opossum testicular interstitial cells showing extensive smooth endoplasmic reticulum involved in testosterone synthesis.
In this historic 1961 paper, Smooth Endoplasmic Reticulum (SER) is called "agranular endoplasmic reticulum", because of the absence of attached ribosomes (RER). SER is abundant in cells involved in steroidal hormone synthesis.
Figure legend
A view at higher power of interstitial cell cytoplasm, showing the elaborate meshwork of interconnecting tubules which constitutes the agranular endoplasmic reticulum. There is biochemical evidence indicating that this reticulum is involved in the biosynthesis of the steroid hormones secreted by these cells. At the upper right is one of the small bodies (b) commonly seen in the cytoplasm. original image X 33,000.
