These examples of ependymal epithelium from the rat brain represent epithelia that lack zonulae occludentes. Further, there appears to be no consistent order to the junctional specializations that are...

Electron micrograph of the junctional complex of intestinal epithelial cells of the rat shows the apical-most zonula occludens (tight junction), the zonula adherens (medium junction) and the macula ad...

A time-lapse movie showing the dorsal pouch formation and migration of heart-anchoring cells (HANCs) in the Drosophila embryo expressing ubi-DE-cad-GFP (Shg-GFP). Shg-positive HANCs corresponding to t...

This is a view of apical domains of two adjacent hepatocytes showing the junctional complexes that attach cells to one another. The canaliculus is defined by the cell membranes of two adjacent liver c...

This is a view of apical domains of two adjacent hepatocytes in the guinea pig liver, showing the junctional complexes that attach cells to one another. The bile canaliculus (BC) is defined by the cel...

Portion of a proximal convoluted tubule from a rat kidney with experimental hemoglobinuria. A mass of dense hemoglobin completely fills the tubule lumen and outlines the microvilli of the brush border...

Portion of a proximal convoluted tubule from a rat kidney with experimental hemoglobinuria. A mass of dense hemoglobin completely fills the tubule lumen and outlines the microvilli (MV) of the brush b...

A 3D reconstruction of the cardiac outflow tract (OFT)(horizontal rotation) from a stage-16 wild-type embryo stained for Ladybird early (Lbe; blue), Tinman (Tin; red), and the DE-Cadherin Shotgun (Shg...

Junctional complex between two cells in the epithelium of the rat intestinal mucosa. The tight junction (also known as zonula occludens) is the structure located nearest to the lumen. The elimination ...

Junctional complex between two cells in the epithelium of the rat intestinal mucosa. The tight junction (also known as zonula occludens, ZO) located nearest to the lumen extends from arrow 1 to arrow ...
