Localization of Adherens Junction Proteins along the Possible Sliding Interface between Secretory Ameloblasts of the Rat Incisor

Abstract

Localization of junctions between inner enamel-secretory ameloblasts was examined by immunofluorescence microscopy using antibodies against adherens junction proteins, radixin, vinculin, and A-CAM. All antibodies used stained the boundary between the ameloblasts exclusively in the plane where F-actin was abundant. This suggests that the adherens junctions in the ameloblasts are involved in cellto-cell movement with actin-based microfilament bundles. © 1990, Japan Society for Cell Biology. All rights reserved.
