Pregnant women's stem cells could treat osteoporosis, say scientists

Stem cell infusions could treat babies affected with rare bone conditions, as well as older people - and even astronauts who lose bone mass in orbit

People with fragile bones could have their skeletons beefed up with infusions of stem cells harvested from pregnant women, researchers say.

Scientists proposed the unusual therapy after studies showed that the treatment led to 78% fewer fractures in animals that were bred to have a brittle bone disorder.
