Primary cilia play a powerful role in how cells sense their surroundings. They help guide embryo development and ensure ...

By tracking the fate of individual embryonic stem cells, researchers have found that endoderm cells—early embryonic cells ...

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 ...

Two teams of scientists have announced that they have grown embryo-like structures, made entirely from human stem cells, that are more advanced than any previous efforts. The synthetic embryos ...

Caltech researchers have developed a powerful new method for creating embryo-like structures from stem cells that could ...

Sixty percent of miscarriages are caused by the failure of an embryo—the developmental stage before a fetus—to implant in the woman’s uterus. Part of the problem is that researchers have no idea how ...

Transforming human stem cells into embryo-like structures was previously unthinkable. Yet seemingly overnight, multiple teams published initial results that reach towards this goal. Each team has a ...

Human embryo development and early organ formation remain largely unexplored due to ethical issues surrounding the use of embryos for research as well as limited availability of materials to study. In ...

A small tissue fold in fly embryos, once thought purposeless, plays a vital role in stabilizing tissues. Researchers show that it absorbs stress during early development, and its position and timing ...

A six-legged mouse embryo, with extra limbs in place of genitals, has been engineered by scientists. It sounds like sci-fi, we know – but the curious creature, which also has several of its internal ...
