The discovery of 280-million-year-old reptile embryos in Brazil and Uruguay has provided paleontologists with the oldest known fossil evidence of amniote embryos. The remains, linked to the aquatic ...

Researchers at the Francis Crick Institute have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four ...

A research group led by Associate Professor Masayoshi Tokita explored the molecular basis generating the diversity of amniote skull morphology, using embryos of several amniote species as materials.

Collaborative work has developed a cell culture system that differentiates human pluripotent stem cells to amniotic ectoderm and surface ectoderm based on cell density. Research conducted by Dr Shota ...
