Fifty-seven swine embryos (10-235 mm in CRL) were examined for the existence of juxtaglomerular cell granules (JGG) in the mesonephros and metanephros. Bowie's staining method was used to demonstrate JGG. (1) JGG of the mesonephros appeared first in an embryo 12 mm in CRL and showed the heaviest granulation in an embryo 20 mm in CRL. They could not be observed in embryos more than 67 mm in CRL. (2) JGG of the metanephros appeared first in an embryo 62 mm in CRL and persisted even in an embryo 235 mm in CRL. (3) The Indices of juxtaglomerular cell granules (JGI) were determined on the adult kidney and the metanephos in two groups consisting of embryos 62 to 89 mm in CRL and embryos 109 to 235 mm in CRL respectively. They were 10.8, 2.1 and 5.2 on an average, respectively. It was known that the metanephros developed with an increase in the number of glomeruli with JGG.
