A stretch of DNA in the mouse genome left by ancient viral infections is crucial for early development in the womb, new research shows. According to the study, published in December in the journal ...

Scientists have created a 6-legged mouse embryo with an extra pair of hindlimbs at the expense of their external genitalia. But far from creating a monster, this rudimentary rodent provides important ...

A rodent with two extra limbs instead of genitals shows the crucial role of a gene pathway in determining the fate of a primordial structure. Developmental biologist Moisés Mallo, at the Gulbenkian ...

The creation of a woolly-mouse embryo marks a significant leap in the field of de-extinction, bringing us one step closer to reviving the iconic woolly mammoth. By combining advanced gene-editing ...

Magdalena (Magda) Zernicka-Goetz, today a developmental and stem cell biologist at the University of Cambridge and California Institute of Technology, recalled being an artistic child who enjoyed ...

A novel screening strategy for identifying embryogenesis-related factors by integrating frozen one-cell embryos, inhibitor libraries, RNA-seq analysis, and genome-editing approaches. A research team ...

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 ...
