Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

Live imaging of embryos at different stages. Chromosomes are labeled in magenta. 4-cell sister blastomeres are shown, along with 3D-reconstructed images of 2-to-4-cell and 4-to-8-cell divisions.

A new discovery by researchers at the RIKEN Center for Biosystems Dynamics (BDR) in Japan upends decades of assumptions regarding DNA replication. Led by Ichiro Hiratani and colleagues, the ...

The International Society for Stem Cell Research (ISSCR) Embryo Models Working Group has released updated recommendations for the oversight and regulation of stem cell-based embryo models (SCBEM), ...

A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...

Glycolysis is an ancient metabolic activity. It consists of a set of reactions that convert glucose into energy. This central process allows cells to grow, divide, and stay alive. It has accompanied ...
