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 ...

The stem-cell-derived embryos could shed new light on the earliest stages of human pregnancy. Mouse embryos recently generated from stem cells in a lab show more brain development than any synthetic ...

A comparison of a natural (top) and synthetic (bottom) mouse embryo, which shows similar brain and heart formation. Photo: Amadei and Handford Scientists in the UK say they’ve pulled off a feat of ...

A stretch of viral DNA in the mouse genome gives cells in early-stage embryos the potential to become almost any cell type in the body. When you purchase through links on our site, we may earn an ...

Scientists have created “synthetic” mouse embryos from stem cells without a dad’s sperm or a mom’s egg or womb. The lab-created embryos mirror a natural mouse embryo up to 8½ days after fertilization, ...

Image of mouse embryos at the 2-cell stage visualised by light microscopy. Two blastomeres (cells) can be seen inside the zona pellucida (a “shell-like” protective outer layer) of each embryo. Credit: ...

A team of scientists in the UK have created “synthetic” mouse embryos without egg or sperm cells. It’s a breakthrough in the field of genetic engineering that could potentially lay the groundwork for ...

As humans gear up for an era of exploring places like the Moon and Mars, a big question arises: can humans reproduce in space? In many ways, we’re still far out from a definitive answer, and ...
