NEW YORK (AP) — Researchers have found that a simple lab treatment can turn ordinary cells from mice into stem cells.
The surprising new study that's being described in the journal Nature hints at a possible new way to grow tissue for treating illnesses like diabetes and Parkinson's disease.
Researchers in Boston and Japan exposed cells from spleens of newborn mice into a more acidic environment than they are used to. In lab tests, that turned them into stem cells -- with enough versatility to produce the tissues of a mouse embryo, for example.
Scientists hope to harness stem cells to replace defective tissue in a wide variety of diseases. By making stem cells from the patient, they can get around the problem of transplant rejection.

Researchers in Boston and Japan say they created stem cells from various tissues of newborn mice. If the same technique works for humans, it may provide a new way to grow tissue for treating illnesses like diabetes and Parkinson's disease.
