In a new study published in Nature Cell Biology, Sophie Petropoulos, a researcher at both Université de Montréal’s affiliated hospital research centre, the CRCHUM, and the Karolinska Institutet, in ...

The first few days of a human embryo’s development, known as pre-implantation, are important. It’s when the first cells are formed, and these decide if the embryo can survive, how it will implant in ...

The guinea pig serves as an alternative model to study human preimplantation development. Nature Cell Biology, 2025; 27 (4): 696 DOI: 10.1038/s41556-025-01642-9 ...

A new study reveal for the first time that the guinea pig pre-implantation embryo is very similar to the human embryo, spurring a better understanding of infertility and early human development.

Over the years, various models have been able to replicate different facets of human embryogenesis, such as amniotic sac development, germ layer formation and body plan organization.

Human embryo, 38 mm, at 8 weeks to 9 weeks old. Embryonic development, also known as embryogenesis, is a cornerstone in understanding the origins of life. But studying this marvel of intricate and ...

Early human development is a complex, multistep process that’s even more complicated to study in the lab. Models made from stem cells avoid some of the trouble with using real human embryos.

Embryonic development, also known as embryogenesis, is a cornerstone in understanding the origins of life. But studying this marvel of intricate and layered biological processes in people faces ...
