Getting it over the finish line was a labor of love—and now, more than five years after her death, the lab of former Sloan ...

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

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

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 ...

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

Scientists have, for the first time, used an extremely precise genome editing technique called base editing to study gene ...

Using CRISPR-based engineering methods to prompt stem cells to organize into embryo-like structures, scientists were able to create 'programmable' cellular models of embryos without ever experimenting ...

During embryonic stem cell (ESC) development, pluripotent stem cells transition from a naïve state into a primed state before they take their first steps toward a lineage commitment. Jacob Hanna, a ...

Modern IVF treatment can now achieve substantially higher success rates than historical approaches while dramatically ...

Men have nipples because embryos are sexually neutral for their first six weeks. Here's the developmental blueprint behind one of anatomy's most overlooked mysteries.
