Abstract
Enzymatic dispersion and density gradient (Percoll) sedimentation were used to isolate a population of renin-containing, granule-laden cells (density 1.067 g/ml) from rat kidney cortex. Using immunohistochemistry (light microscopy) and electron microscopy, we defined the presence and ability of these cells to store renin protein(s). A 1000 base pair rat renin complementary DNA was used to show that these cells express the renin gene. The reverse hemolytic plaque assay defined the functional properties of the renin-containing cell. The data are consistent with the postulated inverse relationship between calcium concentration and release of renin. Thus, we have isolated a population of functional rat kidney cells that synthesize, store, and release renin.
