The Virtual Human Embryo
Welcome to The Virtual Human Embryo (VHE), a 14,250-page, illustrated atlas of human embryology, which presents all 23 Carnegie Stages of development during the 8-week embryonic period.
This $3.2 million, 11-year initiative engaged a team led by Dr. Raymond F. Gasser—one of the leading embryologists of the last half century. His team created thousands of restored, digitized, and labeled serial sections from the world's largest collection of preserved human embryos. They used these serial sections to create animations, fly-throughs, and 3-D reconstructions.
The VHE is now available to researchers, educators, and students everywhere. Read More...
