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 team of scientists has just gotten a closer peek into one of the earliest and most fundamental steps of creating a human life. Research out today highlights how they captured—for the first ...

Stem cell-based embryo models (SCBEMs) are three-dimensional lab-created structures that replicate early human embryo development, providing researchers with critical insights into normally ...

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 ...

a fetus 's physical features as it develops in its mother's womb are primarily shaped by genetic factors, but a new study led by a team at University College London has found that the pressures an ...

Scientists have developed an experimental way to study how human embryos implant in a uterus, which may provide new insights ...

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 ...

Implantation, one of the most poorly understood phases of early human development, occurs in the depths of the womb, at a ...

Scientists have for the first time grown human embryos outside of the mother for almost two full weeks into development, giving unique insight into what they say is the most mysterious stage of early ...

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 ...
