3D Embryo lets the user 
rotate the embryo freely 
around any axis.

At 19 days, the first signs of the nervous system.

Day 23-28; the embryo rapidly goes through remarkable changes in shape.

At 23 days, the folding 
of the brain.

At 23 days, the ability to visualize inner structures is demonstrated.

At 27 days.

At 28 days, the basic body shape is established. “Buds”, head, umbilical cord, and a tail be seen.

3D Embryo model at 28 days (after fertilization), This is the wireframe model used to create 3D images like the others shown on this page.

At 21 days, the folds of the early brain.

At 23 days. The heart 
begins to beat.

At 24 days, the folding brain.

At 28 days.

Cultured neuronal stem cells, scanning electron 
microscopy image.

Living stem cells from the brain, light microscope.

At 28 days, the early eye is seen.

The pelvic floor, from the project “3D Pelvic Floor”.
