The Embryo Project Encyclopedia | Recording and contextualizing the science of embryos, development, and reproduction.

Mitochondria

All cells that have a nucleus, including plant, animal, fungal cells, and most single-celled protists, also have mitochondria. Mitochondria are particles called organelles found outside the nucleus in a cell's cytoplasm. Read more...
Student Training at the Embryo Project

Student training is one of the core missions of the Embryo Project. Students have written dozens of theses based on their research in the Embryo Project. Topics include stem cells, fertilization, genetic screening, and representations of development in textbooks. Here Cera Lawrence explains her research at a poster session. Read more...
Reproductive Health Arizona (RHAZ)

Reproductive Health Arizona (RHAZ) is a project at Arizona State University. Launched in 2016, it aims to record the history of reproductive health, medicine, and biology in Arizona. To do so, it publishes encyclopedia articles, oral histories, maps, and other resources that tell historical stories about those topics and situate them in their historical contexts. All of those items are collected on this page. Read more...
Normal Tables

Normal Tables are visual standards for the development of a species. Explore the history of normal tables in this exhibit, and compare original microscope slides and normal table images. Read more...
Viktor Hamburger

Viktor Hamburger was an embryologist who became best known for his work in neural development, but made significant contributions to studies of induction and developmental genetics. Read more...
Thomas Hunt Morgan

Morgan may have won a Nobel Prize for his work on Drosophila genetics, but he was an embryologist by training and avocation. He made significant contributions to the study of regeneration and experimental embryology more generally. Read more...
1897 MBL Embryology Class

The Marine Biological Laboratory (MBL) in Woods Hole, Massachusetts, began in 1888 to offer opportunities for instruction and research in biological topics. As the lab grew, it added sets of lectures that made up courses in zoology, then botany, then physiology, and in 1893 what became the first Embryology Course. Read more...
Marine Biological Laboratory

The Marine Biological Laboratory in Woods Hole, Massachusetts is a mecca for developmental biologists who teach, take courses, visit the library, or spend the summer in a lab. The Embryo Project is documenting the MBL’s role in the history of embryology, ranging from the early work on cell lineage by EB Wilson, EG Conklin, and Thomas Hunt Morgan to recent interest in regenerative medicine.
