history of stem cells timeline
Aug. 9, 2001 — President George W. Bush signs an order authorizing the use of federal funds for research on a limited number of existing human embryonic stem cell lines. (Click here for the President’s remarks.) Scientists fear several of these available lines are now too old for research.
March 9, 2009 — President Barack Obama signs Executive Order 13505 to repeal some of the restrictions on human embryonic stem cell research funds placed by the previous administration. The order requires the National Institutes of Health to draft new guidelines for federal funding policies within 120 days.
2001, Bush controversy
US president George W. Bush limits federal funding of research on human embryonic stem cells because a human embryo is destroyed in the process. But Bush does allow continued research on human embryonic stem cells lines that were created before the restrictions were announced.
1998, Stem cells go human
James Thomson of the University of Wisconsin in Madison and John Gearhart of Johns Hopkins University in Baltimore, respectively, isolate human embryonic stem cells and grow them in the lab.
Researchers at Cedars-Sinai Medical Center and Johns Hopkins University publish results from a clinical trial in which adult stem cells were extracted from patients following a heart attack. The stem cells were grown in a petri dish and were then returned to the patient’s heart. In the first demonstrated case of therapeutic regeneration, the treatment decreases scarring and leads to regrowth of heart tissue.
In the 110th Congress, the Senate passes their version of The Stem Cell Research Enhancement Act (S. 5) with strong bipartisan support, 63-34. The House also passes the Senate’s version of the bill 247-176. Again, the bill is vetoed by President Bush, and again Congress cannot override the veto.
In 2006, researchers made another breakthrough by identifying conditions that would allow some specialized adult cells to be “reprogrammed” genetically to assume a stem cell-like state. This new type of stem cell is now known as induced pluripotent stem cells (iPSCs).
Scientists discovered ways to derive embryonic stem cells from early mouse embryos nearly 30 years ago, in 1981.
2004 – California voters approve Proposition 71, creating the state’s stem cell agency, the California Institute for Regenerative Medicine
1998 – Jamie Thompson at the University of Wisconsin identifies human embryonic stem cells and grows them in the lab
