For the first time, a stem cell model has produced a structure resembling an early human embryo with a yolk-sac-like structure, from a single starting stem cell population and without direct genetic ...

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 ...

Embryos in pregnancies that end in miscarriage take longer to develop in the womb than those in pregnancies that result in live births, according to new research published today (Monday) in Human ...

A 250-million-year-old fossil from Africa reveals that early mammal ancestors laid eggs, offering insight into their survival ...

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 ...

Intrauterine growth restriction contributes to high rates of “runt” piglets, which have a lower survival rate after birth.
