Multicellularity is one of the most profound phenomena in biology, and relies on the ability of a single cell to reorganize ...

Neural crest cells are a population of stem cells that invade the embryo in early development. They play a big role in what ...

Studying the shape of tissues and organs is critical to understanding how they are formed. Embryonic development happens in ...

Researchers have used naïve pluripotent stem cells to create an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of ...

The first lineage decisions in mammalian embryonic development are made shortly after a wave of transcriptional activation that acts as a wake-up call for the sleeping embryonic genome to claim the ...

Selecting the healthiest embryo is one of the most important steps in in‑vitro fertilization (IVF), yet it remains one of the ...

Huntington’s disease (HD) was the first neurological disorder to be linked to a mutation in a single gene—a discovery made more than 25 years ago. However, neither the pathogenic mechanisms leading to ...

Researchers have developed the first-ever embryo-like model from human embryonic stem cells, a workaround that will let them examine birth defects and diseases they couldn’t otherwise, given ethical ...

Why do pregnancies last longer in some species than others? Researchers at the Francis Crick Institute have found the clock that sets the speed of embryonic development and discovered the mechanism is ...
