11. STEM CELL (DEFINITION) A cell that has the ability to continuously divide and differentiate (develop) into various other kind(s) of cells/tissues Fetal tissue, cord blood, and adult stem cells Cells differentiated, but can form a number of other tissues Multipotent Some cells of blastocyst (5 to 14 days) Cells can form any (over 200) cell types Pluripotent Cells from early (1-3 days) embryos Each cell can develop into a new individual Totipotent Examples Description Stem cell type

Misconceptions hamper understanding Sources of stem cells: Adult stem cells: bone marrow, blood, muscle, fat, nerves , etc. Umbilical cord stem cells: Umbilical cord blood and placenta Embryonic stem cells: From TABs or (supernumerary) IVFs Embryos made solely for research purposes Embryos made using somatic cell nuclear transfer (SCNT) DNA

39. The Case for Federal Funding “ The only possible source for adequate support of our medical schools and medical research is the taxing power of the Federal Government. Such a program must assure complete freedom for the institutions and the individual scientists in developing and conducting their research work.” b) 1945 US Surgeon General Thomas Parran arguing for the establishment of the National Institutes of Health (NIH)

57. Partial Birth Abortion Currently under consideration by US Supreme Court Challenges constitutionality of Partial-Birth Abortion Act of November 2003. (Nebraska law struck down in 2000) Fails to provide an exception for procedures preformed to protect the health of the pregnant woman. Vaguely written Places undue burden on women seeking abortion. Supporters of the law argued that procedure was never medically necessary.
58. Partial-birth abortion With the ban, Congress targeted an abortion procedure, known medically as "intact dilation and extraction," that involves the partial delivery of a fetus. The skull is then punctured and its contents evacuated to make it easier for the head to pass through the birth canal. Doctors say it is used only in exceedingly rare circumstances (1 in 500). American College of Obstetricians and Gynecologists has said that the procedures banned under the measure -- called "intact dilation and extraction and evacuation" and "dilation and extraction” (D & X) -- are increasingly regarded as the safest abortion procedures during the second trimester of pregnancy.
59. Partial-birth abortion Constitutional issues: Right to privacy Right to life (and definition of life) “ Child” or “Fetus” Interest of the state Freedom of religion Legal versus moral considerations Responsibility to make moral choices

61. Conclusion The religions today, even in their disagreements, serve to focus both our awe at the mysteries of our humanity and our anxieties about our futures. Religious traditions will probably continue to adapt to our changing knowledge of ourselves and our growing powers to modify our nature. In so doing they will perhaps shed some light on our biological origins and on our technological destiny. Ronald Cole-Turner Encyclopedia of Bioethics
62. Your role in 21st century medicine There are still many unanswered questions: As physicians, you will be concerned with the particular details of your patients’ lives. You will face situations in which there will inevitably be uncomfortable choices. You will hope to be able to make those decisions with your patients and for your patients best interests. You will hope to be able to practice with in a legal environment that respects science, knowledge, your training, and your own moral convictions.
