Embryonic stem cells are occupying the minds of most US senators. While it is most pleasing to see cell biology in the limelight, ES cells present the political elite in Washington with one of the ...

Scientists found that fruit fly embryos can develop through multiple genetic paths, not just one. This challenges traditional ideas.

In the mouse developing embryo, she previously demonstrated a bias at the two-cell stage: one cell contributed more to fetal tissue and the other to the placenta. 4 “We know so little about the very ...

More than half of the mammalian genome consists of remnants of ancient viral DNA known as ‘transposable elements’ ─ sequences ...

This study sets the stage for future research into specific ... this study has generated an unprecedented dataset. Early embryo development is a highly dynamic process that is of great interest ...

New international research shines a light on the role of transcription factors during early embryonic development ... are active only in early embryonic stages. The research is published in ...

Human, rabbit and mouse embryos at the same developmental stage: gastrulation (around day 18 of human embryonic development .

However, gastrulation, the period beyond this cutoff, represents when the embryo begins to form the eventual body plan, making it an interesting stage to understand early organogenesis. “We’ve just ...

During early development the precursors to all these ... factors that drive tissue differentiation from the earliest embryonic stage forward. This would permit new understanding of cellular ...

Now - the clever bit. The cells on the inside layer of this very early embryo can make all of the cell types needed in your body. They're called stem cells. The stem cells continue to divide by ...
