The University of Michigan says researchers there have created the state's first human embryonic stem cell line.
The discovery was first reported by The Detroit News. The university announced it officially with a statement Sunday.
Embryonic stem cells can become virtually any tissue in the body, and scientists believe they could one day lead to treatments for Parkinson's disease, spinal-cord injuries and other serious illnesses.
They were first isolated at the University of Wisconsin in 1998.
The University of Michigan says its work was made possible by a 2008 state constitutional amendment that allowed scientists to create embryonic stem cell lines using surplus embryos from fertility clinics.
