A research team reported recently that heart muscle cells grown from induced pluripotent stem cells can integrate into the hearts of monkeys with a state of pressure overload.

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 ...

"This is really a textbook image of a human day-14 embryo," Prof Hanna says, which "hasn't been done before". Instead of a sperm and egg, the starting material was naive stem cells which were ...

During embryonic development, cells start out as pluripotent, or have the potential to become many different cell types ...

These are found in an early embryo. These cells are able to divide continuously. Embryonic stem cells are pluripotent. This means that all of the genes in an embryonic stem cell can be expressed ...
