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, ...

Multicellularity is one of the most profound phenomena in biology, and relies on the ability of a single cell to reorganize ...

Passing on fundamental life lessons from parent to offspring is not unique to humans and animals. Ferns do it too. Not with ...

Embryo development starts when a single egg cell is fertilized and starts dividing continuously. Initially a chaotic cluster, it gradually evolves into a highly organized structure. Scientists have ...

At least 8% of the human genome is genetic material from viruses. It was considered ‘junk DNA’ until recently, but its role in human development is now known to be essential Researchers at the Spanish ...

Rowan University biology professor Natasha Shylo is exploring left-right asymmetry development with a grant from the National Institutes of Health.

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 ...

The first few days of a human embryo’s development, known as pre-implantation, are important. It’s when the first cells are formed, and these decide if the embryo can survive, how it will implant in ...

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 at the University of Connecticut have reported a novel bovine embryonic stem cell line with improved pluripotency ...

NAIROBI, Kenya (AP) — A rhinoceros was impregnated through embryo transfer in the first successful use of a method that conservationists said might later make it possible to save the nearly extinct ...
