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 ...

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 ...

A new experimental design that can sustain mouse embryos outside the uterus means that soon, we may be able to watch ...

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 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 ...
