Electron micrographs show examples of pinocytosis in endothelial cells of blood vessels in the cat myocardium (panels A,B,C and H), and from the choroid rete of the bowfin fish eye. Both types of cell...

This transmission electron micrograph of a section through a late orthochromatic erythroblast (normoblast) from human bone marrow shows shallow depressions along the membrane surface, indicated by arr...

Chick Chorioallantoic Membrane (CAM). This scanning electron micrograph shows a section through part of a chick chorioallantoic membrane. A blood vessel has been fractured in the middle of CAM reveal...

Surface of the zona pellucida surrounding a hamster oocyte. This scanning electron micrograph shows the zona pellicida around a hamster oocyte at high magnification. The zona pellicida has a complex ...
