An international team of experts in embryology and bioethics has published the first white paper on the use of embryonic ...

Embryonic development is one of the most dynamic biological processes in nature. Cells and tissues organize and reorganize ...

A new study reveals that age-related autophagy decline blocks embryo development by triggering a lipid-burning crisis.

Embryo development starts when a single egg cell is fertilized and starts dividing continuously. Initially a chaotic cluster, it gradually evolves into a highly organized structure. Scientists have ...

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 ...

Using CRISPR-based engineering methods to prompt stem cells to organize into embryo-like structures, scientists were able to create 'programmable' cellular models of embryos without ever experimenting ...

For several years, researchers studied human embryonic stem cells (ESCs) to understand the unique features of these pluripotent cells, but on their own, they poorly resembled the complex structures ...

The embryos cannot develop into humans, and are being used to study development in outer space.
