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 ...

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 ...

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 ...

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

During embryonic development, the programmed death of certain cells plays an essential role in shaping organs and allowing proper growth. This cell death is in some cases an effect of autophagy, a key ...

Embryonic development, also known as embryogenesis, is a cornerstone in understanding the origins of life. But studying this marvel of intricate and layered biological processes in people faces ...

When Berna Sozen, PhD, assistant professor of Developmental Stem Cell Biology at Yale, was in her first weeks of pregnancy, she couldn’t help but wonder about what exactly was going on in the “black ...

"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 ...
