Atomic force microscopy of Mammalian urothelial surface.

ABSTRACT: The mammalian urothelium apical surface plays important roles in bladder physiology and diseases, and it provides a unique morphology for ultrastructural studies. Atomic force microscopy (AFM) is an emerging tool for studying the architecture and dynamic properties of biomolecular structures under near-physiological conditions. However, AFM imaging of soft tissues remains a challenge because of the lack of efficient methods for sample stabilization. Using a porous nitrocellulose membrane as the support, we were able to immobilize large pieces of soft mouse bladder tissue, thus enabling us to carry out the first AFM investigation of the mouse urothelial surface. The submicrometer-resolution AFM images revealed many details of the surface features, including the geometry of the urothelial pl
