Cultured juxtaglomerular cells: production and localization of renin.
Trypsin- or collagenase-dispersed renal cortical cells from newborn mice were filtered and cultured. The cultures comprised 25% juxtaglomerular cells as identified by immunocytochemistry. Renin was measured by radioimmunoassay in the culture medium and in the cells at various time intervals. This in vitro system was responsive to isoproterenol, which stimulated renin release in a dose-dependent manner.
