Biologists have long puzzled over how organs develop into their final shapes, and the nearly transparent bodies of young sea ...

Two separate research teams used base editing to make single-nucleotide changes in human embryos this month, targeting genes ...

A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...

Scientists have, for the first time, used an extremely precise genome editing technique called base editing to study gene function in human embryos. They found that a gene called NANOG is essential ...

Because of their ability to simulate certain aspects of embryonic development, stem cell-based embryo models can be a ...

Human embryo models can help researchers study early human development and infertility without relying solely on human ...

A discovery upends decades of assumptions regarding DNA replication. The study show that DNA replication in early embryos is different from what past research has taught, and includes a period of ...

A new study uses precise base editing on human embryos for the first time, proving the NANOG gene is the master switch for body development.
