Notes:
Summary Morphologic studies were performed on the summer cell of Stilling in the interrenal gland of the American bullfrog. Ultrastructural studies showed the cell to be packed with membrane-bound granules similar to those of the juxtaglomerular apparatus granules in the mammalian kidney. These granules reacted positively with several stains for granules of cells in the juxtaglomerular apparatus. The Stilling cells are intimately associated with the cortical cells and contain rough endoplasmic reticulum and granules in varying degrees of development associated with the Golgi apparatus. It is concluded that the Stilling cell may secrete a renin-like substance that may function in an aldosterone-stimulating reninangiotensin system.
