Cuboidal Kidney Cells Labeled. The renal corpuscle is made of parietal cells podocytes and mesangial cells. Additionally a third intermediate pec subgroup was identified at the junction between the flat and cuboidal pec subgroups at the tubular orifice.
The transgenic mouse line pec rtta labeled all three pec subgroups. In the cross section each tubule appears as a ring of cuboidal cells around a white space the lumen of the tubule. Pseudostratified columnar epithelium with stereocilia.
These cells termed cuboidal pecs make up the most proximal part of the proximal tubule and may also line parts of bowman s capsule.
The kidney functions as a complex filtering device that removes excess water and a variety of waste products and maintains the ion and ph balance of the body. The transgenic mouse line pec rtta labeled all three pec subgroups. Additionally a third intermediate pec subgroup was identified at the junction between the flat and cuboidal pec subgroups at the tubular orifice. The lower photo shows a longitudinal section of kidney tubules.
