Transposable elements are stretches of DNA that can move around the genome. Many of these DNA sequences originate from long ago, when viruses inserted their genetic material into our ancestors' ...

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 ...

New international research shines a light on the role of transcription factors during early embryonic development. Transcription factors are proteins that are critical for gene regulation. The study ...

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, ...

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 ...

The new platform's ethically grounded approach promises to reveal much about how human embryos form during the earliest stages of pregnancy. It's one of life's most defining moments -- that crucial ...

Image of mouse embryos at the 2-cell stage visualised by light microscopy. Two blastomeres (cells) can be seen inside the zona pellucida (a “shell-like” protective outer layer) of each embryo. Credit: ...

Researchers have discovered a key transition in early embryonic development is facilitated by decreasing levels of a viral protein inserted into the DNA of our early animal ancestors. Researchers at ...

Researchers developed a method that visualizes gene activity across an entire embryo with high spatial detail. The resulting ...
