The interface between epithelium and lamina propria in the rat urinary bladder.

A Microscopic Study, Mucosal Cells of Urinary Bladder in Streptozotocin Diabetic Rats with Parasite

It has been known that as a result of diabetes several diseases occur in organisms such as parasitic infection. This gives rise to inflammatory conditions associated with mast cells. For the purpose of observing mucosal cells in bladder tissue, streptozotocin diabetic rat bladders were examined with light and electron microscope. A microscopic study of serial sections revealed numerous mast cel...

Contractile activity of the bladder urothelium and lamina propria

Suppression of dysplasia and hyperplasia by calcium in organ-cultured urinary bladder epithelium.

The cause for the development of endophytic growth (nodular downgrowth) in rat urinary bladder epithelia cul tured in protein-free medium was traced to a deficiency of Ca in the culture medium. Endophytic growth, which is a characteristic in vivo histolÃ3gica! feature of the preneoplastic phase of experimental bladder cancer, was induced in vitro by 0.3 mm Ca2" but was suppressed by 1.8 rriM Ca...

[Autoradiographic localization of muscarinic receptors in diabetic rat bladder].

PURPOSE We evaluated the alterations of density, localization and subtype specificity of muscarinic receptors in experimentally-induced diabetic rat bladder. METHODS Five groups of rats were maintained for sixteen weeks 1) diabetic, 2) diabetic insulin-treated (insulin started 8 weeks after the onset of diabetes), 3) sucrose-fed diuretic, 4) sucrose-removed and 5) age matched controls. We use...

Rhythmic Calcium Events in the Lamina Propria Network of the Urinary Bladder of Rat Pups

The lamina propria contains a dense network of cells, including interstitial cells (ICs), that may play a role in bladder function by modulating communication between urothelium, nerve fibers and smooth muscle or acting as pacemakers. Transient receptor potential vanilloid 4 (TRPV4) channels allow cation influx and may be involved in sensing stretch or chemical irritation in urinary bladder. Ur...
