The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...

Embryonic development is a meticulously orchestrated process in which spatial and temporal cues guide cell fate determination and tissue patterning. Central to this process is morphogen signalling – a ...

Embryonic development is a finely orchestrated process in which a single cell differentiates into the myriad specialised tissues that comprise a fully formed organism. Central to this process are ...

Prefer Newsweek on Google to see more of our trusted coverage when you search. What do the earliest stages of a pregnancy look like? Embryonic development has been extensively studied, but most of our ...

Sox9, a master regulator of cartilage formation, switches its target genes dynamically during embryonic limb development ...

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 ...

For the first time, a stem cell model has produced a structure resembling an early human embryo with a yolk-sac-like ...

Konstanz researchers identify an enzyme that plays a role in the migration of cells in our body—not only during normal tissue formation and wound healing, but also when tumor cells metastasize. 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 ...

The annual killifish lives in regions with extreme drought. A research group now reports that the early embryogenesis of killifish diverges from that of other species. Unlike other fish, their body ...
