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 ...

As nearly one in six couples experience fertility issues, in-vitro fertilization (IVF) is an increasingly common form of ...

Nearly half the embryos studied underwent developmental arrest because of genetic mishaps in early development—a revealing insight that suggests more IVF babies could come to term with changes in the ...

When you seek the help of a fertility specialist to conceive, your first step is to undergo diagnostic tests to understand your likelihood of success. This is followed by a comprehensive consultation ...

A gene that turns on very early in embryonic development could be key to the formation of the placenta, which provides 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 ...

Mouse embryo cells undergo apical-basal polarization asynchronously at the 8-cell stage, and the timing of polarization influences subsequent lineage allocation.

A new study examining mouse embryos when they are composed of just two cells, right after undergoing their very first ...
