Stem Cell Policy Map

<div><p>Countries colored in brown have a permissive or flexible policy on human embryonic stem cell research. All have banned human reproductive cloning. These countries represent about 3.4 billion people, more than half the world's population. “Permissive” (countries in dark brown) means that various embryonic stem cell derivation techniques are permitted, including SCNT. “Flexible” (countries in light brown) means that stem cells may be derived from human embryos donated by fertility clinics only, excluding SCNT. Countries in yellow have either a restrictive policy or no established policy.</p> <p>(Image: William Hoffman, MBBNet [<a href="http://www.plosmedicine.org/article/info:doi/10.1371/journal.pmed.0030143#pmed-0030143-b6" target="_blank">6</a>])</p>
