Stem cell laws and policy in the United States have had a complicated legal and political history.

Stem cells are cells found in all multi-cellular organisms. They were isolated in mice in 1981, and in humans in 1998.[1] In humans there are many types of stem cells, each with varying levels of potency. Potency is a measure of a cells differentiation potential, or the number of other cell types that can be made from that stem cell. Embryonic stem cells are pluripotent stem cells derived from the inner cell mass of the blastocyst. These stem cells can differentiate into all other cells in the human body and are the subject of much scientific research. However, since they must be derived from early human embryos their production and use in research has been a hotly debated topic as the embryo most likely is destroyed in the process.

Stem cell treatments are a type of cell therapy that introduce new cells into adult bodies for possible treatment of cancer, diabetes, neurological disorders and other medical conditions. Stem cells have been used to repair tissue damaged by disease or age.[2]Cloning also might be done with stem cells. Pluripotent stem cells can also be derived from Somatic cell nuclear transfer which is a laboratory technique where a clone embryo is created from a donor nucleus. Somatic cell nuclear transfer is also tightly regulated amongst various countries.

Until recently, the principal source of human embryonic stem cells has been donated embryos from fertility clinics. In January 2007, researchers at Wake Forest University reported that "stem cells drawn from amniotic fluid donated by pregnant women hold much of the same promise as embryonic stem cells."[1]

In 2000, the NIH, under the administration of President Bill Clinton, issued "guidelines that allow federal funding of embryonic stem-cell research."[1]

In 1973, Roe v. Wade legalized abortion in the United States. Five years later, the first successful human in vitro fertilization resulted in the birth of Louise Brown in England. These developments prompted the federal government to create regulations barring the use of federal funds for research that experimented on human embryos.[3] In 1995, the NIH Human Embryo Research Panel advised the administration of President Bill Clinton to permit federal funding for research on embryos left over from in vitro fertility treatments and also recommended federal funding of research on embryos specifically created for experimentation. In response to the panel's recommendations, the Clinton administration, citing moral and ethical concerns, declined to fund research on embryos created solely for research purposes,[4] but did agree to fund research on left-over embryos created by in vitro fertility treatments. At this point, the Congress intervened and passed the Dickey-Wicker Amendment in 1995 (the final bill, which included the Dickey Amendment, was signed into law by Bill Clinton) which prohibited any federal funding for the Department of Health and Human Services be used for research that resulted in the destruction of an embryo regardless of the source of that embryo. In 1998, privately funded research led to the breakthrough discovery of human Embryonic stem cells (hESC). Stem cells are cells that have not differentiated yet.

No federal law ever did ban stem cell research in the United States, but only placed restrictions on funding and use, under Congress's power to spend.[5]

In February 2001, George W. Bush requested a review of the NIH's guidelines, and after a policy discussion within his circle of supporters, implemented a policy in August of that year to limit the number of embryonic stem cell lines that could be used for research.[1] (While he claimed that 78 lines would qualify for federal funding, only 19 lines were actually available.[1])

In April 2004, 206 members of Congress, including many moderate Republicans, signed a letter urging President Bush to expand federal funding of embryonic stem cell research beyond what Bush had already supported.
