The first steps of human development—those that occur within the first few weeks of pregnancy—remain mysterious in many ways. Within a week of fertilization, human embryos form a blastocyst, which ...

A faithful model of the human blastocyst has been developed which replicates key phases of very early development from 4 to 13 days post fertilization, including attaching to layers of ...

The study of blastoids, a research model of an early embryo derived from stem cells rather than from a father's sperm or a mother's egg, offers great hope for researchers investigating why pregnancies ...

Innovative research, presented today at the ESHRE 40 th Annual Meeting in Amsterdam, has introduced a novel 3D imaging model designed to identify features of blastocysts – the early stage of ...

Please provide your email address to receive an email when new articles are posted on . The 3D imaging model achieved more than 90% accuracy in identifying blastocyst features. Blastocyst overall ...

The earliest moments of human development—between the time of fertilization and when the embryo implants in the womb—have remained opaque to scientists. Cells in the earliest stages of human ...

In some mammals, the timing of the normally continuous embryonic development can be altered to improve the chances of survival for both the embryo and the mother. This mechanism to temporarily slow ...

The stem cells were no more than a week old when scientists moved them from their slick-walled plastic wells into ones lined with a thin layer of human endometrial tissue. But in that time, the cells ...

For women who are carriers of mitochondrial diseases, one particular in vitro fertilization (IVF) procedure for having a healthy baby appears to be safe, according to new research. This option, called ...
