Patterns that guide the development of feathers and other features can be set by mechanical forces in the embryo, not just by gradients of chemicals. One of the longest-standing questions in biology ...

By comparing 34 different developmental stages across five mammals, the team created a single-cell atlas of early embryonic gene activity that scientists can now explore in depth. “This dataset ...

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.

One often thinks that the early embryo is fragile and needs support. However, at the earliest stages of development, it has the power to feed the future placenta and instructs the uterus so that ...

Researchers haven't been able to study the amnion in detail because current stem cell embryo models don't typically capture later stages of human development and, for ethical reasons, human ...
