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

Glycolysis is an ancient metabolic activity. It consists of a set of reactions that convert glucose into energy. This central process allows cells to grow, divide, and stay alive. It has accompanied ...

In A Nutshell Egg geometry drives development: The curved shape of a zebrafish egg causes unequal cell divisions, creating larger cells near the animal pole and smaller cells at the margin—a size ...

Biologists have provided new insights on a longstanding puzzle in biology: How complex organisms arise from a single fertilized cell. Producing a new 'gene atlas' with 4-D imaging, the researchers ...

Cell division is an essential process for all life on earth, yet the exact mechanisms by which cells divide during early embryonic development have remained elusive – particularly for egg-laying ...

Understanding how cells differentiate during early embryonic development is crucial for advancing regenerative medicine and developmental biology. Pluripotent stem cells (PSCs) have been invaluable ...

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 research team showed that, contrary to current models, one early embryonic cell dominates lineages that will become the fetus. “They are not identical,” said Magdalena Zernicka-Goetz, a ...

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