Conditional genetics and single-embryo RNA-seq show that SETDB1 extinguishes the transient, retroelement-driven transcriptional programs of the totipotent two-cell state to facilitate the exit from ...

Scientists at the University of California, Santa Cruz (UCSC), used CRISPR to engineer cellular models of embryos that mimic what happens in the first few days after reproductive cells meet. These ...

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 ...

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, ...

Researchers have characterized, in exacting detail, the rapid series of events that transform a single fertilized cell into a living, complex being. The work not only has enabled the team to explore ...

Neural crest cells are a population of stem cells that invade the embryo in early development. They play a big role in what ...

Researchers at Vanderbilt University have developed a new embryo culture dish that significantly improves microscope imaging, a longstanding barrier in in‑vitro fertilization (IVF). Traditional 3D ...

Some animals in the world possess the ability to regenerate tissues, allowing them to regrow parts of limbs or entire limbs ...

Pregnant women rely on a balanced diet and supplements to deliver proper nutrients to their babies, to ensure they grow healthfully. Such nutrients contribute to fueling development and providing ...
