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 ...

Research shows how the curved shape of a zebrafish egg sets cell division timing, gene activation, and early cell fate ...

How can we reliably and objectively characterize the speed and various stages of embryonic development? With the help of artificial intelligence! Researchers present an automated method. Animal ...

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 ...

Two to three weeks after conception, an embryo faces a critical point in its development. In the stage known as gastrulation, the transformation of embryonic cells into specialized cells begins. This ...

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 ...

A pair of research teams unveiled two new ways to replicate a key structure from the earliest days of embryonic development — an advance that could provide important new insight into human development ...

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

Fredrik Lanner is in the Department of Clinical Sciences, Intervention and Technology, Karolinska Institutet, Division of Gynecology and Reproduction, Karolinska University Hospital, Stockholm, and ...

As people age, so do all of our cells, which accumulate damage over time. But why our offspring don’t inherit those changes — effectively aging a child even before birth — has been a mystery. “When ...

Living structures that model early human embryonic development have been generated entirely from cells in the skin. The models mean it should be possible to study infertility, early miscarriage and ...
