Transitional Epithelial Cells

Another type of epithelial cell is a transitional epithelial cell, also known as a urothelial cell. It is smaller than a squamous epithelial cell and has a centrally located nucleus. Transitional epithelial cells can occur in spherical, polyhedral, and caudate (bottom image) forms. They originate from the bladder, ureters, and renal pelvis.
