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...

Colorized scanning electron micrograph of Amarylis stigma (pink) with pollen grains (yellow) adhering to sticky glands on its surface. Some pollen tubes (olive green) carrying genetic material can be ...

Scanning electron micrograph showing Penta lanceolata unacetolyzed pollen. Compare this pollen to acetolyzed pollen images by the same contributor in the Library. This image is a ]higher magnificatio...

Electron micrograph of a nerve from the mesentery of a rat shows groups of unmyelinated axons wrapped by deeply invaginating Schwann cells in cross section. Surrounding the Schwann cell wrapping is a ...

During hippocampal neuron development in vitro, N-cadherin becomes selectively localized to excitatory synapses. This image shows immunolocalization of N-cadherin. Other images in this image group sh...

This electron micrograph shows the basal lamina as a thin gray moustache following parallel along the basal membrane of epithelial cells from human corneal epithelium. In this tissue, the basal lamin...

This electron micrograph shows the endothelium and the underlying Descemet's membrane of the human cornea. Descemet's membrane is an unusually thick and structurally specialized example of basal lami...

Boi (red) localizes predominantly to apical cells in Drosophila wild-type germaria but not in germaria with UAS-boi[RNAi] expression (CIL#13742). Germ cells are identified using anti-Vasa (blue). Imag...

Topographical regulation of keratinocyte migration. 2D, 3D, and 1D fibrillar migration of human epidermal keratinocytes. 2D matrices were constructed by uniform coating with extracellular matrix (ECM)...

A freeze fracture replica of a Sertoli cell junction from rat testis shows more than 50 rows of particles along the E-face. Image from Gilula, Fawcett and Aoki, Dev. Biol. 50: 142-168 (1976), reprint...
