Embryos

Biological processes

Embryos from numerous plant and animal species are studied in biological research laboratories across the world to learn about topics such as stem cells, evolution and development, cell division, and gene expression. Examples of scientific discoveries made while studying embryos that were awarded the Nobel Prize in Physiology or Medicine include the Spemann-Mangold organizer, a group of cells originally discovered in amphibian embryos that give rise to neural tissues, and genes that give rise to body segments discovered in Drosophila fly embryos by Christiane Nüsslein-Volhard and Eric Wieschaus.
