In 2005, the National Academies released the book, Guidelines for Human Embryonic Stem Cell Research, which offered a common set of ethical standards for a field that, due to the absence of ...

Scientists have long dreamed of plucking those naive cells from a young human embryo and coaxing them to perform, in sterile isolation, the everyday miracle they perform in wombs: transforming ...

A stem-cell derived human embryo model showing blue cells (embryo), yellow cells (yolk sac) and pink cells (placenta). Scientists have grown an entity that closely resembles an early human embryo ...

After years of trial and error, scientists have finally done something incredible: They have successfully grown human stem cells in a pig embryo. Why would anyone do this? Turns out, many ...

The little clump of cells looked almost like a human embryo. Created from stem cells, without eggs, sperm, or a womb, the ...

For the first time, Oregon State researchers in the US have used cloning techniques to create human embryonic stem cells that could offer hope for conditions such as Parkinson's disease ...

The development of human synthetic embryos was announced at the annual meeting of the International Society for Stem Cell Research. Synthetic embryos are also known as "embryo models", as they ...

US President Barack Obama has reversed some barriers to human embryonic stem cell research, but much remains to be done to ensure that stem cell research flourishes in the US in the coming decades.

Substrates with concave curvatures resembling those found in the developing embryo mechanically revert mouse and human pluripotent stem cells into a naivety-like state. Two independent studies ...
