Lab grown models of embryos, made from clusters of stem cells, are getting increasingly complex. Ethicists, regulators and ...

When they analyzed the embryoids, the scientists noted that 80% of the stem cells organize themselves into a structure that mimics a basic embryo after a few days. Most had undergone gene ...

The tiny mouse embryo has a heart that beats. Its muscles, blood vessels, gut and nervous system are beginning to develop. But this embryo is unusual: It was made in a lab, out of mouse embryonic stem ...

Self-organization of mouse embryonic stem cells into reproducible pre-gastrulation embryo models via CRISPRa programming. Cell Stem Cell, 2025; DOI: 10.1016/j.stem.2025.02.015 ...

A team at Kobe University has created a game-changing resource for autism research: 63 mouse embryonic stem cell lines, each carrying a genetic mutation strongly associated with the disorder. By ...

A mouse created with stem cells from a choanoflagellate Sox gene, left, and a “wild type” mouse. The lab-induced stem cells had genetic markers like dark eyes.

Researchers in Japan have successfully generated lung cells similar to alveolar epithelial type 2 (AT2) cells from mouse embryonic fibroblasts without using stem cell technology. The AT2-like ...
