Cell compaction is a crucial step in embryo development. Defective compaction prevents the formation of the structure that ensures an embryo can implant in the uterus. This stage is carefully ...

A new study examining mouse embryos when they are composed of just two cells, right after undergoing their very first ...

Scientists have created a stem cell-derived model of the human embryo in the lab by reprogramming human stem cells. The breakthrough could help research into genetic disorders and in understanding why ...

Scientists have developed a mouse model that could be a promising model system for research into factors affecting mammalian embryonic development and disease. The National Institute of Health (NIH) ...

A gene that turns on very early in embryonic development could be key to the formation of the placenta, which provides the ...

A human embryo-like model was successfully developed by a group of scientists at the California Institute of Technology, led by renowned biologist Madalena Zernicka-Goetz. The model replicates the ...

AP — Scientists have created embryo models to help study the mysteries of early human development, the medical problems that happen before birth, and why many pregnancies fail. These models are made ...

A discovery upends decades of assumptions regarding DNA replication. The study show that DNA replication in early embryos is different from what past research has taught, and includes a period of ...

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 ...

Many top UK scientists are calling for the current 14-day limit on embryo research to be doubled to 28-days, so they can study the unexplored secrets of early human development. Lifting the ban could ...
