BRASILIA, Brazil — Brazil’s Supreme Court ruled Thursday that scientists can conduct embryonic stem-cell research, which holds the promise of curing Parkinson’s disease and diabetes but raises ethical concerns.
Six of the court’s 11 justices upheld a 2005 law allowing embryonic stem-cell research and turned down a petition filed that same year by then- Attorney General Claudio Fontelles, who argued the law was unconstitutional because it violates the right to life.
The National Conference of Brazilian Bishops issued a statement saying it “regretted” the ruling, comparing it to a death sentence. The bishops’ conference said its position “is not a matter of religion, but of the defense of human life, beginning with conception.”
