Doctors have treated a baby with brittle bone disease while still in the womb, using stem cell technology. The Swedish team took genetically unmatched cells from another foetus to treat the unborn girl, who had been diagnosed with Osteogenesis Imperfecta. The condition means she is especially prone to fractures but she is now two- and-a-half and has only suffered three - fewer than might have been expected. But Karolinska Institute researchers said stem cell therapy was not a cure.
