By tracking the fate of individual embryonic stem cells, researchers have found that endoderm cells—early embryonic cells ...

The use of assisted reproductive technologies like in vitro fertilization is becoming more common worldwide. However, while ...

A study in newborn chicks shows that brain lateralisation is essential for the development of a left-to-right mental number line.

Lateralization of the brain – the tendency for the left and right hemispheres to specialize in different functions – underlies the development of a left-to-right mental number line, according to a ...

Despite being an essential developmental process, the understanding of human embryonic genome activation is limited, owing to the lack of in vitro cell models and ethical concerns. To advance ...

Embryonic development is a meticulously orchestrated process in which spatial and temporal cues guide cell fate determination and tissue patterning. Central to this process is morphogen signalling – a ...

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 ...
