Targeted stem-cell attack could make transplants safer

INA – SOURCES

Blood stem-cell transplants show promise for treating genetic and immune disorders, as well as cancers, but are currently risky.

Scientists are experimenting with ways to selectively target the body’s blood-making cells for destruction.

Early studies in animals and people suggest that the approach could make blood stem-cell transplants powerful but dangerous procedures that are used mainly to treat blood cancers safer, and thereby broaden their use.

The studies come as evidence piles up that such transplants can also treat some autoimmune disorders and genetic diseases.
