During early development, tissues and organs begin to form through the shifting, splitting, and growing of many thousands of cells. A team of researchers headed by MIT engineers has now developed a ...

That first pulse of life, the careful, patterned movement of cells that creates a new organism, has always been something of a secret miracle. Now, MIT engineers have introduced a deep-learning model ...

Only two weeks after fertilization, the first sign of the formation of the 3 axes of the human body (head/tail, ventral/dorsal, and right/left) begins to appear. At this stage, known as gastrulation, ...

Toward the goal of generating high-quality embryo models in vitro, this study establishes a stepwise protocol to derive trophectoderm-like cells from mouse extended pluripotent stem (EPS) cells. These ...

The development of synthetic embryo models using early stem cells has emerged as a powerful platform for studying mammalian development in vitro. However, the generation of high-quality ...

In Victorian Europe, hairwork jewelry was a popular means of remembering the departed. Family or friends would snip lockets of hair — or the dying individual would cut a locket himself and give it to ...

In 2018, Chinese scientist He Jiankui shocked the world when he revealed that he had created the first gene-edited babies. Using Crispr, he tweaked the genes of three human embryos in an attempt to ...

As cattle have not been traditionally considered a model species and the molecular details of germ cell development don’t directly inform production practices, the specification of primordial germ ...

ST. LOUIS — Samantha was an embryo frozen in time for approximately a decade before a middle-aged single mother said yes to her birth. That mother was Dawn Jones-Goldstein, a 46-year-old Eureka woman ...

A team of researchers at the Institute for Bioengineering of Catalonia (IBEC) in Spain has succeeded, for the first time, in recording in real time and in 3D the implantation of a human embryo. This ...

Researchers have captured the very first real-time, three-dimensional images and videos of a human embryo implanting into collagen designed to mimic uterine tissue —a key stage in reproduction. The ...
