It’s challenging to sustain a pregnancy when food is short, or conditions are otherwise tough. That’s why many mammalian embryos can postpone their growth to get through periods of environmental ...

The earliest stages of mammalian embryo development are like an orchestra performance, where everyone must play at the exact right moment and in perfect harmony. New research identifies one of the ...

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 ...

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 cells ...

Live imaging of an early mouse embryo expressing fluorescent markers for cell membranes (magenta) and DNA (cyan). The right side shows a digitized version of the same embryos at the 8-cell stage. This ...

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 ...

Around 700 million years ago, the animal kingdom began to branch off from single-celled organisms. Now, scientists have uncovered molecular tools that could have assisted the leap — and successfully ...
