A research team from the University of Nevada, Las Vegas, has developed a way to quadruple the number of stem cells harvested from extracted wisdom tooth root pulp. The stem cells are being studied for their ability to treat a variety of medical conditions.

Tooth roots are especially appealing to scientists and medical researchers because they are home to two types of valuable stem cells. Pluripotent stem cells can become almost any type of cell while multipotent stem cells can become very specific types of cells.
