A new discovery by researchers challenges our current understanding of gastrulation, the most important stage of early embryonic development. When the zygote, or the fertilised egg, starts to develop, ...

When the zygote, or the fertilised egg, starts to develop, the soon forming inner cell mass, a cluster of cells that will eventually develop into the individual, retains its pluripotent stem cell ...

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 ...

A stretch of viral DNA in the mouse genome gives cells in early-stage embryos the potential to become almost any cell type in ...

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 ...

Scientists have uncovered a new way embryonic cells divide when conventional mechanisms fail. Cell division underpins all ...

The image shows cross sections from four different developmental stages in the early embryo from gastrulation (flat) to the end of neurulation. Unexpectedly, the study revealed that stem cells that ...

A recent Nature study evaluates post-implantation development in humans using embryo-like models based on genetically unmodified human naïve embryonic stem cells (ESCs). Study: Complete human day 14 ...

Molecular mechanism uncovered in mice by UC Santa Cruz researchers reveals how a father’s diet, stress, and other ...
