A new study using stem cell-based models has shed new light on how the human embryo begins to develop, which could one day benefit the development of fertility treatment. A new study using stem ...

For several years, researchers studied human embryonic stem cells (ESCs) to understand the unique features of these pluripotent cells, but on their own, they poorly resembled the complex structures ...

What makes every person unique? Part of the answer is in our genes.

(CNN) -- A human embryo, containing about a couple hundred cells, is smaller than the period at the end of a sentence. Scientists need strong microscopes to see these precursors to life, and to take ...

Almost 14 months after President Bush first allowed federal funding of human embryo cell research, U.S. scientists remain frustrated by a lack of access to the controversial cells, researchers told a ...

WASHINGTON (Reuters) - Stem cells made from human embryos can home in on damaged eyes, hearts and arteries of mice and rats, and appear to start repairs, a U.S. company said on Monday. Sign up here.
