Tissue‐engineered Artificial Urothelium

World Journal of Surgery, 2000
AbstractBladder wall replacement is one of the most challenging problems of urologic surgery. Various materials have been tried in experimental models, but most were not free of complications, such as leakage, infection, and stone formation. In addition, much time was needed for tissue regeneration after grafting.

Urothelium-specific antibody and lectin surface mapping of bladder urothelium

The Histochemical Journal, 1982
Coupled ligand-colloidal gold complexes were found to provide a convenient approach for the localization of scanning electron microscopy of cell surface membrane antigens and lectin-binding sites on bladder urothelium and for the immunocytochemical identification of urothelial cell populations at different stages of differentiation. The ligands used to

Vesical Urothelium and New Concepts

Urologia Journal, 2012
Vesical urothelium was long considered to simply be a protection barrier, which passively separates the urinary content from the underlying smooth muscle and the blood stream. Recent observations, though, have pointed out that vesical urothelium cells have clear active and sensory functions, in response to various physical and chemical stimuli.

Tissue engineering in urothelium regeneration

Advanced Drug Delivery Reviews, 2015
The development of therapeutic treatments to regenerate urothelium, manufacture tissue equivalents or neourethras for in-vivo application is a significant challenge in the field of tissue engineering. Many studies have focused on urethral defects that, in most cases, inadequately address current therapies.

28K Antigen in the Urothelium

Journal of Urology, 1992
We have been investigating the nature of the mucosal lining of human urinary bladder. Surface material was obtained from bladders at autopsy and used for biochemical analysis. Western immunoblotting and tissue immunochemistry identified a molecule of Mr 28,000 (28K) which is present within surface cells of the urothelium (umbrella cells).

Mechanotransduction in the urothelium

2023
The urothelium, which covers the inner surface of the bladder, is continuously exposed to a complex physical environment where it is stimulated by and responds to a wide range of mechanical cues. Mechanically activated ion channels allow the urothelium to convert mechanical stimuli into biochemical events that influence its surface area and the ...

Cultured urothelium in sheep bladder augmentation

Pediatric Surgery International, 1996
In search of alternatives for urothelial-lined augmentation or reconstruction of the urinary bladder, this study combined the application of seromuscular gastrointestinal (GI) segments with the use of in-vitro cultured, autologous urothelial cells in a sheep model. A cell culture system was set up for establishment and expansion of urothelial cells out

Formation and regeneration of the urothelium

Current Opinion in Organ Transplantation, 2014
This review addresses significant changes in our understanding of urothelial development and regeneration. Understanding urothelial differentiation will be important in the push to find new methods of bladder reconstruction and augmentation, as well as identification of bladder cancer stem cells.This review will cover recent findings including the ...

Effects of Formalin on Bladder Urothelium

Journal of Urology, 1975
Formalin instillation into canine bladders was followed by serial radiographic and histologic evaluation. A generalized slough of epithelial tissue was seen with the deposition of an amorphous substance. Telangiectasia resulted in moderate bleeding.
