Stem Cells Sci Basics 07/20/05 Question?? Who were the most influential people of the past century? James Watson (L) and Francis Crick (R), and the model they built of the structure of DNA (and Rosalind Franklin).

Stem Cells Sci Basics 07/20/05 Topics  Stem Cells – The Basics  Cloning – Therapeutic and Human  The Politics – State, National, International

Stem Cells Sci Basics 07/20/05 Stem Cell History Researchers first extract stem cells from human embryos First Successful human transplant of insulin-making cells from cadavers President Bush restricts federal funding for embryonic stem-cell research Juvenile Diabetes Research Foundation International creates $20 million fund-raising effort to support stem-cell research California ok stem cell research Harvard researchers grow stem cells from embryos using private funding Ballot measure for $3 Billion bond for stem cells

Stem Cells Sci Basics 07/20/05 Importance  Disease Diabetes, Spinal cord injury, Parkinson’s disease, heart disease  Genetic based Disease Cystic fibrosis, Huntington’s

Stem Cells Sci Basics 07/20/05 Stem Cell Characteristics  ‘Blank cells’ (unspecialized)  Capable of dividing and renewing themselves for long periods of time (proliferation and renewal)  Have the potential to give rise to specialized cell types (differentiation)

Stem Cells Sci Basics 07/20/05 Cloning for use in Stem Cells Cloning techniques for creating stem cells Therapeutic cloning Reproductive cloning

Stem Cells Sci Basics 07/20/05 IVF – In Vitro Fertilization  Available since 1986  About 100,000 IVF kids in U.S.  Often creates extra embryos  U.S. - About 400,000 frozen embryos (unregulated)  England – 52,000 (regulated by government)

Stem Cells Sci Basics 07/20/05 What Americans Think From Research!America Taking Our Pulse: The PARADE/Research!America Health Poll Charlton Research Company, 2005 July 10, 2005

Stem Cells Sci Basics 07/20/05 Do you think the U.S. is performing well or performing poorly compared to other nations in terms of science and math education? Taking Our Pulse: The PARADE/Research!America Health Poll Charlton Research Company, 2005 U.S. Performance in Science and Math Education

Stem Cells Sci Basics 07/20/05 Taking Our Pulse: The PARADE/Research!America Health Poll Charlton Research Company, 2005 A Majority of Americans Favor Embryonic Stem Cell Research Do you favor or oppose medical research using embryonic stem cells? 58% 29%

Stem Cells Sci Basics 07/20/05 Taking Our Pulse: The PARADE/Research!America Health Poll Charlton Research Company, 2005 A Majority of Americans Favor Research Using Donated Eggs from Fertility Clinics Scientists can extract embryonic stem cells from fertilized eggs that are voluntarily donated by fertility clinic patients. These fertilized eggs would otherwise be discarded. Knowing this, do you favor or oppose embryonic research?

Stem Cells Sci Basics 07/20/05 Taking Our Pulse: The PARADE/Research!America Health Poll Charlton Research Company, 2005 A Majority of Americans Favor Cloning Technology to Make Embryonic Stem Cells Scientists can now make embryonic stem cells for medical research by merging an unfertilized egg with a skin cell, for example. In other words, no fertilization takes place and there is no merger of egg and sperm. Knowing this, do you favor or oppose embryonic stem cell research?

Stem Cells Sci Basics 07/20/05 Taking Our Pulse: The PARADE/Research!America Health Poll Charlton Research Company, 2005 Therapeutic Cloning Should Be Allowed Therapeutic cloning is the use of cloning technology to help in the search for possible cures and treatments for diseases and disabilities. Do you think that research into therapeutic cloning should be allowed?

Stem Cells Sci Basics 07/20/05 WA State Legislation WA State Stem Cell Bills "Regulating stem cell research“ (passed House on 3/15/05 and failed in the Senate on 4/11/05) Forum on Science Ethics and Policy (FOSEP – at UW)

Stem Cells Sci Basics 07/20/05 State Legislation – Key Points  Informed Consent  No reproductive Cloning  IRB approval

Stem Cells Sci Basics 07/20/05 California Legislation  Law supports therapeutic cloning  $3 Billion bond measure to support stem cell research

Stem Cells Sci Basics 07/20/05 National Regulation  President Bush restricts federal funding for embryonic stem- cell research  Federal funding only for existing stem cell lines  Many consider inadequate

Stem Cells Sci Basics 07/20/05 National Legislation  House of Representatives passed the Stem Cell Research Enhancement Act (H.R. 810)  Senate is expected to consider it soon - corresponding bill (S.471) today!

Stem Cells Sci Basics 07/20/05 International Legislation  South Korea – refined nuclear transfer or therapeutic cloning  China – supports research  Singapore – stem cell research a national priority  Israel – leaders stem cell disease  Great Britain – leader Dolly – active support of research  Japan – supports research
