Organoids produce embryonic heart

There was a time when the idea of growing organs in the lab was the stuff of science fiction. Today, stem cell biology and tissue engineering are turning fiction into reality with the advent of organoids: tiny lab-grown tissues ...

New insights into early embryonic development

The majority of pregnancies that fail do so at a very early developmental stage, before the pregnancy is even detectable by tests. This critical stage, occurring about a week after fertilization, is when an embryo implants ...

Molecular puzzle reveals unknown stages of fetal development

By applying gene analysis to individual cells from early mouse embryos, researchers at Karolinska Institutet in Sweden have discovered previously unknown cellular stages of fetal development from fertilised egg to living ...

Stem cells organize themselves into pseudo-embryos

The definitive architecture of the mammalian body is established shortly after implantation of the embryo in the uterus. The antero-posterior, dorso-ventral and medio-lateral axes of the body become organized under the control ...

Bovine embryos as a model for early human development

The mechanisms that underlie early embryonic development in humans and cattle are very similar. Therefore, LMU researchers argue that bovine embryos might well be a better model for early human development than the mouse ...

Synchronised waves control embryonic patterning

During an embryo's journey from a single cell to a complex organism, countless patterning processes make sure that the right cells develop in exactly the right location and at the right time. Cells activate specific genes ...
