Scientists Coax Human Embryonic Stem Cells Into Making Insulin

Insulin is produced by the green cells that are in clusters about the same size as the islets in the human pancreas. The red cells are producing another metabolic hormone, glucagon, that prevents low blood sugar. Harvard University hide caption

Scientists Coax Human Embryonic Stem Cells Into Making Insulin

Researchers have found a way to mass- produce the pancreatic cells that are insulin factories inside the body. The findings could eventually lead to treatments that would transform diabetes care.

Scientists Create Fertile Eggs From Mouse Stem Cells

For the first time, scientists have created fertile eggs and healthy offspring using embryonic stem cells. The experiments in mice raise the possibility of artificial egg production and new infertility treatments for humans someday.

First Hints That Stem Cells Can Help Patients Get Better

Sue Freeman, 78, is one of two women who appear to have unexpectedly regained some of their vision while taking part in a study testing the safety of an embryonic stem-cell therapy. The findings, if confirmed, could mark a landmark step in stem cell therapy, but everyone involved in the work is being very cautious about how they describe these results.
