In a separate experiment, they instructed the stem cells to form a beating, heart-like structure, complete with a central chamber and a network of blood vessels.

One is that immature stem cells may still be lurking among the mature cardiomyocytes, and they could go on to form tumors after implants. That wasn't seen in this case.

Using computer-designed proteins, researchers can now direct human stem cells to form new blood vessels in the lab. This advance in regenerative medicine offers new hope for repairing damaged ...

A single infusion of a stem cell-based treatment may have cured 10 out of 12 people with the most severe form of type 1 diabetes. One year later, these 10 patients no longer need insulin.
