Researchers have used stem cells to develop new human embryolike structures that model the earliest stages of fetal development so realistically that they even secrete hormones that can turn a lab ...

Researchers have created a replica of womb lining or endometrium which allowed them to study the implantation of human embryos — process that signals start of a pregnancy. Described in a paper in the ...

Scientists have created a stem cell-derived model of the human embryo in the lab by reprogramming human stem cells. The breakthrough could help research into genetic disorders and in understanding why ...

For decades, scientists have struggled to study this moment in humans because of ethical restrictions and limited access to ...

Researchers have characterized, in exacting detail, the rapid series of events that transform a single fertilized cell into a living, complex being. The work not only has enabled the team to explore ...

In a recent study published in the journal Science Immunology, researchers profile the origins and subsequent differentiation of embryonic and fetal immune cells during human lung development. Study: ...

A stylized representation of different stages of prenatal development in mice. Researchers at The Jackson Laboratory provided a critical level of precision necessary for the accurate computational ...
