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, the Hiiragi ...

The two cells that make up a one-day-old human embryo might look identical at first glance. But a study 1 published today shows that most of the human body forms from only one of those cells — a ...

The beginning of life is shrouded in mystery. While the intricate dynamics of mitosis is well-studied in the so-called somatic cells – the cells that have a specialized function, like skin and muscle ...

From the moment an embryo starts to take shape, two-way communication is critical for making sure tissues and organs develop correctly.

By engineering a system replicating the womb lining with high biological accuracy, researchers at the Babraham Institute and ...

As nearly one in six couples experience fertility issues, in-vitro fertilization (IVF) is an increasingly common form of reproductive technology. However, there are still many unanswered scientific ...

Scientists are exploring ways to mimic the origins of human life without two fundamental components: sperm and egg. They are coaxing clusters of stem cells – programmable cells that can transform into ...

The team placed blastocysts—embryos 5-6 days after fertilization that were donated following IVF procedures—onto the ...

Magdalena (Magda) Zernicka-Goetz, today a developmental and stem cell biologist at the University of Cambridge and California Institute of Technology, recalled being an artistic child who enjoyed ...

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 ...

Scientists are using AI to better predict embryo health in real time. Embryologists are the scientists behind the scenes of in vitro fertilization who oversee the development and selection of embryos, ...
