Changes in cellular metabolites have been shown to regulate embryonic stem cell development at the earliest stages of life. Metabolites are simple compounds generated during life-sustaining chemical ...

China has delivered the world's first human artificial embryo models to orbit to test how microgravity affects human ...

Embedded within the mammalian life cycle is a highly organised progression from fertilisation through preimplantation stages, blastocyst formation, implantation and subsequent axis establishment and ...

The findings shed light on the origins of congenital heart defects and could open new avenues in regenerative medicine and tissue bioengineering. A study published today in the journal Developmental ...

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 ...

Researchers have discovered a key transition in early embryonic development is facilitated by decreasing levels of a viral protein inserted into the DNA of our early animal ancestors. Researchers at ...

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 ...

Microgravity and higher radiation levels in orbit could disrupt cell alignment, gene expression, or organ formation.
