In the recent work, stem cells were derived from a human embryo days after fertilization and transformed with chemical prodding in tissue culture into a mass of cells possessing characteristics of the pancreatic cells that secrete insulin, the researchers said.
Embryonic stem cells, which can develop into any type of cell in the human body – and thus have vast research and medical potential – are usually grown from a mass of cells harvested from the embryo; the procedure destroys the embryo.
