Electron micrograph of a cultured Drosophila DL1 cell infected with flock house virus, prepared using chemical fixation followed by routine embedding for electron microscopy. This specimen was prepare...

The movie illustrates two approaches to understanding the 3D structure of complex objects, using the pluteus stage embryo of the sea urchin Arbacia punctulata. The first sequence is a through-focus DI...

Light micrograph of a human embryo at the blastocyst stage, about six days after fertilization. The embryo is in the process of "hatching" out of the zona pellucida - the tough outer membrane - just b...

A human sixteen-cell embryo, also called a morula (latin for mulberry). The embryo has gone through four cycles of cell division to get to this stage and the cells have undergone compaction whereby th...
