Toward the goal of generating high-quality embryo models in vitro, this study establishes a stepwise protocol to derive trophectoderm-like cells from mouse extended pluripotent stem (EPS) cells. These ...

Model used to create a cellular ‘hologram’ of a mouse embryo could be used to visualize development in any species. Researchers have created the most detailed 3D cellular map yet of a mouse embryo, ...

The normal mouse embryo at left is in its eighth day of development and has structures that mark the beginnings of its brain, heart and other organs. At right is a comparably developed synthetic ...

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 ...

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 ...

Growing tissues can crack, break, and dissociate to form structures that can later withstand immense forces.

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 ...
