Missouri Constitutional Amendment 2 (The Missouri Stem Cell Research and Cures Initiative) was a state constitutional amendment initiative that concerned stem cell research and human cloning. It allows any stem cell research and therapy in the U.S. state of Missouri that is legal under federal law, including somatic cell nuclear transfer to produce human embryos for stem cell production. It prohibits cloning or attempting to clone a human being, which is defined to mean "to implant in a uterus or attempt to implant in a uterus anything other than the product of fertilization of an egg of a human female by a sperm of a human male for the purpose of initiating a pregnancy that could result in the creation of a human fetus, or the birth of a human being".[2] Commercials supporting and opposing the amendment aired during the 2006 World Series, in which the St. Louis Cardinals participated.[3] The issue became especially intertwined with the 2006 U.S. Senate election in Missouri, with the Republican and Democratic candidates on opposite sides of the issue.
Missouri Constitutional Amendment 2 appeared on the ballot for the November 2006 general election and passed with 51% of the vote.[4]
