A scientific researcher works with embryonic stem cells from in-vitro fertilization in a laboratory, at the Univestiry of Sao Paulo’s human genome research center, in Sao Paulo, Brazil, on March 4, 2008. Brazil’s Federal Supreme Court will decide tomorrow on the continuity of the embryonic stem cells research, after Roman Catholich church officials and anti-abortion groups urged to ban it, as the stem cells extraction entails the destruction of the embryo.
