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 ...

Embryo development starts when a single egg cell is fertilized and starts dividing continuously. Initially a chaotic cluster, it gradually evolves into a highly organized structure. Scientists have ...

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 ...

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 ...

In 2021, KAUST highlighted joint work on blastoid models intended to mimic parts of the blastocyst stage without creating a viable embryo, and in 2025 it publicised “deepBlastoid”, an artificial ...

For the first time, a stem cell model has produced a structure resembling an early human embryo with a yolk-sac-like structure, from a single starting stem cell population and without direct genetic ...

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 ...

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