urothelial cell intermediate cell of urothelium 2023-06-16T07:53:43Z A urothelial cell that is part of the regenerative layer(s) of cells directly superficial to basal cells in urothelium. The layer of intermediate cells in the urothelium ranges from one to several layers thick depending on the species with intermediate cells attached to adjacent cell layers and one another via desmosomes. https://orcid.org/0000-0003-3065-9183 urothelial intermediate cell FMA:84155 It has been noted in at least some mammalian species that the urothelial intermediate cell type is similar to basal cells by expressing CK17 and (unlike umbrella cells) p63 but is positive for uroplakins (UPK) and negative for CK5. Urothelial intermediate cells have also been noted to be larger in diameter than urothelial basal cells.
