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 ...

Stem cells that give rise to the mouse yolk sac have been isolated and cultured in the lab for the first time by RIKEN researchers, raising the possibility of artificially creating mouse embryos from ...

The endoderm layer destined to be primitive gut is a mosaic of earlier visceral endoderm and definitive endoderm that arises later, during gastrulation. Live imaging now reveals that in mouse embryos, ...

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 ...

Pluripotent stem cells, created from human skin or mouse ear tissue, are shown here becoming endoderm cells. The endoderm is one of the three primary germ layers that ultimately contribute to 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 ...

Scientists from Helmholtz Zentrum München revise the current textbook knowledge about gastrulation, the formation of the basic body plan during embryonic development. Their study in mice has ...

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 ...

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 ...
