Summary
In the epithelium of the mucous membrane in the rectum of rats there are some cells with the following pecularities:
-
1.
Glycogen-particles which form extended accumulations in young animals, but are singly distributed in adults.
-
2.
A brush-border, the microvilli of which are larger and thicker than in the adjoining border cells.
-
3.
Bundles of filaments and rows of vesicles in the apical part of the cytoplasm.
These glycogen containing brush-cells are very similar to the sensory cells we have described in the epithelium of the trachea of the rat; so far however we have been unable to find connections with dendrites.
Zusammenfassung
Zwischen den gewöhnlichen epithelialen Zellen der Wand des Rectum der Ratte befinden sich Zellen mit folgenden Besonderheiten:
-
1.
Glykogenpartikel in Anhäufungen bei jüngeren Tieren, als vereinzelte Granula bei erwachsenen.
-
2.
Ein Bürstensaum, dessen Mikrovilli länger und dicker sind als die der anliegenden Saumzellen.
-
3.
Filamentbündel und Reihen von Vesikeln im apikalen Zellteil.
Diese glykogenhaltigen Bürstenzellen gleichen den Sinneszellen, die wir im Epithel der Trachea der Ratte festgestellt haben; eine Verbindung mit Dendriten konnten wir aber bisher nicht nachweisen.
