Sox9, a master regulator of cartilage formation, switches its target genes dynamically during embryonic limb development ...

Scientists at the University of California, Santa Cruz (UCSC), used CRISPR to engineer cellular models of embryos that mimic what happens in the first few days after reproductive cells meet. These ...

Scientists have discovered a method of helping human stem cells thrive in an animal embryo—a key development in efforts to grow human organs in animals for medical transplants. A study by UT ...

An international study led by the medical Faculty of the University of Bonn has identified a gene that plays an important role in the development of the human embryo. If it is altered, malformations ...

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 ...

A robust and quantitative map links chromatin modification and gene expression of cells during zebrafish embryogenesis.

Which genes are required for turning embryonic stem cells into brain cells, and what happens when this process goes wrong? In a new study published today in Nature Neuroscience, researchers led by ...

Chromosphaera perkinsii is a single-celled species discovered in 2017 in marine sediments around Hawaii. The first signs of its presence on Earth have been dated at over a billion years, well before ...

For the first time, a stem cell model has produced a structure resembling an early human embryo with a yolk-sac-like ...

A breakthrough in genetics reveals how spines first appeared, changing what we know about the evolution of complex species.
