It may someday be possible for doctors to create new immune systems in people who have autoimmune diseases.
The science is very preliminary, but Stanford researchers say they've done it using specially designed mice by transplanting new blood-forming stem cells into the animals' bone marrow. Those cells then established a new blood and immune system.
The research might eventually benefit people with genetic disorders or defective immune systems, as in Multiple Sclerosis.
