Muscularis mucosae - the forgotten sibling.
Lamina muscularis mucosae sitting beneath mucosal surface of the digestive tract has received little attention to date compared with external smooth muscle layers. Motor activity of the muscularis mucosae shows a great regional and species difference. Autonomic innervation profile is also different from esophagus to colon or between animal species. Intracellular transduction mechanisms for moto...
متن کاملAntigenic Profile of Muscularis Mucosae and Muscularis Propria of the Urinary Bladder
Background: Differentiation between the muscularis mucosae (MM) and muscularispropria (MP) of the bladder remains challenging. Objective: To identify MM- and MP-specific antigens that could be of potential value for staging of urothelialcarcinomain a pilot study. Method: The expression of 12 protein antigens in 11 human bladder specimens was examined. There were 5 post radical cystectomy specim...
متن کاملTetrodotoxin-sensitive and -insensitive action potentials in myotubes.
The study of long-term cultures of myogenic cells has proven that electrical excitability develops only after the development of electrical coupling between the cells. That is, neither surface contact in itself nor coupling in itself is sufficient to cause excitability to develop in these cells. Following the formation of multinucleated myotubes, several different types of electrical responses ...
متن کاملImmunohistochemical evaluation of the muscularis mucosae in the ruminant forestomach.
The muscularis mucosae and condensed fibrous layer of the ruminant forestomach were studied by immunohistochemistry using specific antibodies against alpha-smooth muscle actin (alphaSMA) and gamma-smooth muscle actin (gammaSMA). The specimens were collected from the rumen, reticulum and omasum of cattle, water buffalo, sheep, goat, Barbary sheep, Japanese serow, sika deer and mouse deer. The mu...
متن کاملPhenotypic change of muscularis mucosae in early invasive colorectal adenocarcinoma.
BACKGROUND Invasive colorectal adenocarcinomas have bundles of eosinophilic spindle cells, which are regarded as myofibroblasts, in their desmoplastic stroma, some of which are continuous with the muscularis mucosa. AIM To investigate the relation between the eosinophilic spindle cells and the muscularis mucosa based on their cytoskeletal phenotypes in early invasive colorectal adenocarcinoma...
