Abstract

Juxtaglomerular (JG) cells in two-kidney Goldblatt hypertensive (2KGH) rats were examined ultrastructurally. In JG cells of the clipped kidneys of 2KGH rats, microcanaliculi branched off from channel-like invaginations of plasma membrane and connected with the secretory renin granules. These findings suggest that micro-canaliculi may play important role in renin secretion from JG cells in 2KGH rats.
