The development of an embryo is one of the most fundamental processes in biology. Early in this process, it is determined ...

The sperm and the egg cell's nuclei compete for size directly after fertilization and this is necessary for proper embryonic ...

Two separate studies have uncovered surprising physical principles guiding early embryo development. German researchers found DNA methylation patterns in embryos follow universal dynamic rules, while ...

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 at LMU have discovered that early embryonic DNA methylation patterns follow universal physical principles, challenging the view of epigenetics as purely biochemical. The team showed that ...

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 ...

For the first time, a stem cell model has produced a structure resembling an early human embryo with a yolk-sac-like structure, from a single starting stem cell population and without direct genetic ...

Over half of our genomes consists of thousands of remnants of ancient viral DNA, known as transposable elements, which are widespread across the tree of life. Once dismissed as the "dark side" of the ...

NEW YORK -- New lab techniques have provided the first good look at a crucial but mysterious stage in the development of human embryos, scientists reported Wednesday. The researchers said follow-up ...
