Ultrastructure of putative steroid-producing cells in the gonads of coho ( Oncorhynchus kisutch ) and pink salmon ( Oncorhynchus gorbuscha )
The testes of coho and pink salmon apparently contain both interstitial (Leydig) cells and lobule boundary cells. The interstitial cells possess cellular organelles characteristic of steroid-producing cells (large mitochondria with tubulovesicular cristae and an extensive agranular endoplasmic retic...
