Scanning electron microscope image of Strongylocentrotus drobachiensus [sea urchin] at the gastrula stage. Embryo was split open to reveal the blastocoel cavity. There are several migrating mesenchyme...

Scanning electron microscope image of Strongylocentrotus drobachiensus [sea urchin] embryo at the late gastrula stage. This is a high magnification image of CIL 39785. Embryo was cut to reveal blastoc...

Scanning electron microscope image of Strongylocentrotus drobachiensus [sea urchin] at the gastrula stage. Embryo was cut in half to reveal blastocoel cavity, containing blastocoel matrix material, pr...

Image of the scopula, the stalk forming region at the aboral end of the cell body of Opercularia coarctata. A group of basal bodies each gives rise to a modified cilium that gives rise to a cylinder o...

Transmission electron micrograph of thin section of rat liver with prominent Golgi and smooth ER associated vesicles. At lower right, the junction between hepatocytes harbors a bile canaliculus. The i...

This image shows a group of secretory vesicles loaded with very low density lipoproteins (VLDLs) located near the sinusoidal cell membrane (CM) of a hepatocyte. The fate of these VLDLs is to be secret...

This historic micrograph features the Golgi complex from a hepatocyte of a rat treated with ethanol to stimulate lipoprotein synthesis. The cisternae are distended and loaded with very low density lip...
