Neural crest cells have been thought to originate in the ectoderm, the outermost of the three germ layers formed in the earliest stages of embryonic development. But their capacity to form derivatives ...

Scientists have created the first detailed day-by-day map of human embryo development using single-cell technology.

Proceedings of the National Academy of Sciences of the United States of America, Vol. 118, No. 23 (June 8, 2021), pp. 1-10 (10 pages) Markers for the endoderm and mesoderm germ layers are commonly ...

How do cells turn into organs? During embryonic development, three germ layers form, known as the endoderm, the mesoderm, and the ectoderm. These germ layers give rise to different parts of the ...

News Sea Anemones Illuminate the Evolution of Embryo Development A study of a simple marine animal suggests that the common ancestor of cnidarians and bilaterians may have had three germ layers ...

Researchers offer a phylogenetic and ontogenetic overview of the primitive streak and its role in mediating amniote (vertebrate animals that develop on land) gastrulation, and discuss the implications ...

STANFORD, Calif. — More than 2,000 genetic regions involved in early human development have been identified by researchers at the Stanford University School of Medicine. The regions, called enhancers, ...

When planning a trip, it's rare that you don't have a choice of route. One may be more direct, another more scenic; but regardless of the time or route taken, the destination is the same. This concept ...

Human embryo development and early organ formation remain largely unexplored due to ethical issues surrounding the use of embryos for research as well as limited availability of materials to study. In ...

In their publication in Science, Professor Guojun Sheng (Kumamoto University, Japan), Professor Alfonso Martinez Arias (Universidad Pompeu Fabra, Spain) and Professor Ann Sutherland (University of ...
