A research team led by Associate Professor Hirofumi Nishizono and graduate student Masaki Kato from the Research Support ...

Technological, ethical and legal issues have limited the understanding of the early stages of embryonic development in humans, despite its importance in basic developmental biology and reproductive ...

Cell division is an essential process for all life on earth, yet the exact mechanisms by which cells divide during early ...

The curved shape of a zebrafish egg causes unequal cell divisions, creating larger cells near the animal pole and smaller ...

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 ...

In a scientific breakthrough that raises a number of medical and ethical issues, researchers have used stem cells to create living, growing models of a human embryo. Because stem cells were used, ...

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 ...

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 ...

A team of scientists in Sweden has broken open the genetic recipe for a human embryo's first three days of development, chronicling what happens in the crucial hours that follow the union of egg and ...

Researchers have developed the first-ever embryo-like model from human embryonic stem cells, a workaround that will let them examine birth defects and diseases they couldn’t otherwise, given ethical ...

A discovery upends decades of assumptions regarding DNA replication. The study show that DNA replication in early embryos is different from what past research has taught, and includes a period of ...

The donation of a miniscule human embryo the size of a poppy seed has given scientists an extremely rare glimpse into an early stage of human development that has long been difficult to study, the ...
