The majority of fertilized eggs die and are resorbed into the body. ZEISS Microscopy/Flickr, CC BY-SA As an evolutionary biologist whose career has focused on how embryos develop in a wide variety of ...

Researchers have created human embryos by taking nuclei from ordinary skin cells, placing them into donated eggs, and ...

The team used human stem cells to create embryo-like structures dubbed “hematoids” that mirror some features of early human ...

Scientists have created the first detailed day-by-day map of human embryo development using single-cell technology.

Using human stem cells, scientists have created human embryo-like structures inside petri dishes. These lab-grown blobs develop multiple structures that mimic a human embryo after implantation into ...

Despite being an essential developmental process, the understanding of human embryonic genome activation is limited, owing to the lack of in vitro cell models and ethical concerns. To advance ...

A recent Nature study evaluates post-implantation development in humans using embryo-like models based on genetically unmodified human naïve embryonic stem cells (ESCs). Study: Complete human day 14 ...

A review in Clinical Epigenetics synthesizes growing evidence that paternal lifestyle and environmental exposures such as diet, obesity, smoking, endocrine-disrupting chemicals, and stress alter sperm ...

Scientists have used an experimental approach to form human eggs in the lab that can then be fertilized ... skin cells likely weren't successfully reprogrammed to sustain embryonic development. In ...

Our ancient past isn't always buried history. When it comes to our DNA, nearly 9% of the human genome is made up of leftover genetic material from ancient viruses (called endogenous retroviruses or ...
