Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires ...

Researchers have used naïve pluripotent stem cells to create an embryo model that looks and acts like a natural human embryo. They say it’s an ethical way of gaining a better understanding of ...

Scientists have uncovered a new quality control system that removes damaged cells from early developing embryos. Scientists studying gene activity data of the early human embryo have discovered an ...

There is variability in when and how cells divide during the development of embryos. While researchers traditionally believed this variability was an obstacle that needed to be regulated, a group now ...

Years of work by developmental biologists from Trinity College Dublin, working with colleagues at the University of Edinburgh's MRC Human Genetics Unit, has yielded a resource of unparalleled detail ...

For nearly three days after a sperm meets an egg, the human embryo (a tiny, eight-cell blob) is managed by the egg’s genes. On day three, the embryo strips its entire genome naked, freeing itself of ...

A MedUni Vienna study team led by geneticist Markus Hengstschläger has used a stem cell model to model the earliest stages of embryonic development and to characterize the membrane that surrounds the ...

High-resolution 3D womb model gives insights into embryo implantation, infertility, and signals between embryo and mother, ...

Early in development, all animal embryos pass through an almost identical stage where they form a blastoderm, which is a hollow ball of a few thousand cells. From that hollow ball, layers of cells ...

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 ...
