Researchers have discovered a new type of stem cell that resembles cells in the early human embryo during the transition of 'genomic power' from mother to embryo. During this major developmental event ...

There is variability in when and how cells divide during the development of embryos. While researchers traditionally believed this variability was an obstacle that needed to be regulated, the Hiiragi ...

A stem cell–derived human embryo model at a developmental stage equivalent to that of a day 14 embryo. The model has all the compartments that define this stage: the yolk sac (yellow) and the part ...

Using single-cell sequencing and spatial tools, researchers have created the most comprehensive map of the maternal–fetal interface yet.

Researchers announce the development of a mouse embryo model, complete with beating hearts and the foundations for a brain and other organs, out of mouse embryonic stem cells. Just two weeks after ...

During embryonic stem cell (ESC) development, pluripotent stem cells transition from a naïve state into a primed state before they take their first steps toward a lineage commitment. Jacob Hanna, a ...

The early beginnings of an embryo as it transforms from a clump of cells to a tiny human is a bit of a mystery — scientifically speaking. We know many of the broad strokes, but there are a lot of ...
