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 ...

In the earliest stages of life, mammalian embryos start as a disorganized cluster of cells. As development progresses, these cells become organized into well-defined shapes and structures. This ...

Despite being an essential developmental process, the understanding of human embryonic genome activation is limited, owing to the lack of in vitro cell models and ethical concerns. To advance ...

Researchers led by developmental biologist Kathy Niakan at the University of Cambridge have used base editing in human embryos to learn more about human embryonic development. By deactivating a gene ...

Two to three weeks after conception, an embryo faces a critical point in its development. In the stage known as gastrulation, the transformation of embryonic cells into specialized cells begins. This ...

In the earliest hours after fertilization, an embryo takes its first steps toward becoming a living organism by shedding maternal control and activating its own genetic program. This critical process, ...

A human embryo model replicates key early developmental processes and generates organ-seed cells in vitro. [Photo provided to ...

"Guinea pigs can become a valuable model for understanding how early disturbances in embryonic development can affect health later in life. Since guinea pig development mirrors that of humans better ...
