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

In the earliest hours after fertilization, an embryo takes its first steps toward becoming a living organism by shedding maternal control and activating its own genetic program. This critical process, ...

Transposable elements are stretches of DNA that can move around the genome. Many of these DNA sequences originate from long ...

Scientists have developed an experimental way to study how human embryos implant in a uterus, which may provide new insights into why miscarriages occur and how they can be prevented.

What do the earliest stages of a pregnancy look like? Embryonic development has been extensively studied, but most of our knowledge of the earliest stages of a growing baby come from stationary ...

A lot happens in the first month of human embryo development as a single cell morphs into multitudes. Yet despite its significance, this period is basically a “black box” to researchers, says stem ...

A research team showed that, contrary to current models, one early embryonic cell dominates lineages that will become the fetus. “They are not identical,” said Magdalena Zernicka-Goetz, a ...

A new study from the MRC Laboratory of Medical Sciences (LMS) in London, UK reveals how ancient viral DNA once written off as ...

The new organoids were grown in the lab for up to 40 days, and they mimicked the central nervous system of an 11-week-old human embryo. When you purchase through links on our site, we may earn an ...

Seals give birth only when conditions are right. After mating, a female seal can delay implantation of the embryo in the ...
