[Sex difference and fine structure on epithelium cells of Bowman's capsule in mice (author's transl)]

Bowman's capsules with cuboidal epithelium were found in 87.2%, 95.5%, 75.4%, 96.7%, 98.8% and 91.2% in the kidney of adult male C57BL/6J-ob, JCL-ICR, dd, E1, ASK and KK mice, respectively, while in 57.9%, 6.7%, 7.0%, 2.8% and 9.1% in adult female C57BL/6J-ob, JCL-ICR, dd, E1 and ASK mice, respectively. The renal corpuscles with cuboidal epithelium in Bowman's capsules of male JCL-ICR mice increased gradually in number from 5 to 10 weeks age. The surface of cuboidal epithelium cells was shown to have long cilia and dense microvilli, which were similar to those seen in proximal uriniferous tubules.
