Effects of extracellular osmolality on renin release and on the ultrastructure of the juxtaglomerular epithelioid cell granules

O Skøtt et al. Cell Tissue Res. 1987 Aug.

Abstract

Superfusion with hypoosmotic solutions stimulates renin release from rat epithelioid cells adherent to isolated glomeruli. This stimulatory effect may be related to the observed swelling of the secretory granules; the swelling may markedly increase the probability of pre-exocytotic fusions between the granule and cell membranes, and consequently increase the frequency of exocytotic events.
