Study finds early-stage ectoderm cells are especially susceptible, raising questions about potential developmental risks ...

Cell division is an essential process for all life on Earth, yet the exact mechanisms by which cells divide during early embryonic development have remained elusive—particularly for egg-laying species ...

Researchers at the Francis Crick Institute have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four ...

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 ...

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 ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

Egg cells need to store large amounts of proteins and other molecules to support the earliest stages of development. But how ...

High-resolution imaging reveals a large protein complex in egg cells that stores key developmental molecules. The structure ...
