The electron micrograph shows the tip of a primary cilium in a testis cell in primary culture. The plasma membrane of the adjacent cell has a coated pit juxtaposed to the ciliary tip.

Total internal reflection (TIRF) micrograph of MDCK cells stably transfected with the apical membrane protein P75-GFP (green) and stained for acetylated tubulin of the primary cilium (red) by immunofl...

Scanning electron micrograph of the apical surface of neuromast organ of lateral line system in a 17-day-old zebrafish. The hair bundles at the top of each sensory cell emerge through a pore in the ...

High resolution image on the multiple membrane systems at the cortex of ciliates. Thickened alveolar densities partially coat the alveolar membrane within the alveoli which underlie the plasma membran...
