Gastrulation leads to three germ layers—ectoderm, mesoderm and endoderm—that are separated by two basement membranes. In the mouse embryo, the emergent gut endoderm results from the widespread ...

An unexpectedly versatile and regenerative stem cell in early embryos may be key to creating new effective fertility treatments, suggests a new study in mice from the University of Copenhagen. It ...

The third type of stem cells that make up the precursors of mouse embryos has been established for the first time Stem cells that give rise to the mouse yolk sac have been isolated and cultured in the ...

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 ...

How did the gut, the skin and musculature evolve? This question concerns scientists for more than a century. Through the investigation of the embryonic development of sea anemones, a very old animal ...

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 ...

Scientists revise the current textbook knowledge about gastrulation, the formation of the basic body plan during embryonic development. Their study in mice has implications for cell replacement ...

Summary Scientists in the Sloan Kettering Institute have combined powerful laboratory and computational techniques to analyze the earliest moments of mouse development. The results could help explain ...
