Title: Stem Cell Research


1
Stem Cell Research
  • Legal, Ethical and Policy Questions

2

3
What is a Stem Cell?
  • The original cells from which all other cells are
    derived
  • Pluripotent stem cells
  • Plenipotent stem cells

4
How are Stem Cells Derived?

7
How are Stem Cells Derived?
  • Embryonic Stem Cells
  • Embryos at very early stages
  • Fetal stem cells
  • Aborted fetuses (spontaneously or by intention)
  • Placenta
  • Umbilical cord blood
  • Adult stem cells

8
What Does the Law Say?
  • Clinton Administration
  • Moratorium on embryonic stem cell research
  • Bush Administration
  • Compromise in Fall of 2002
  • Use of stem cell lines

9
What Does the Law Say?
  • Permissible
  • Adult stem cells
  • Placenta
  • Umbilical cord blood
  • Aborted fetuses
  • Not aborted for the sole purpose of obtaining
    stem cells

10
What Does the Law Say?
  • Not Permissible
  • Embryonic stem cells
  • Embryos created for research
  • Compromise
  • Current stem cell lines
  • Approximately 70
  • Dozen laboratories worldwide

11
The Ethics of Embryonic Stem Cell Research
  • Are these scientifically necessary?
  • Yes
  • Potential for treatments of many types of
    diseases (e.g., early indications in Parkinsons)
  • Cannot stop scientific progress
  • Embryos at this stage are potential humans but
    not human
  • There are numerous embryos available in IVF
    clinics that could be donated

12
The Ethics of Embryonic Stem Cell Research
  • Are these scientifically necessary?
  • No
  • Difficulties with getting these cells to
    express and differentiate into various types
    of cells and tissue
  • Problems with viability and condition of frozen
    embryonic stem cells
  • Adult stem cells are in plentiful supply

13
The Ethics of Embryonic Stem Cell Research
  • The Case for valuing embryos as human life and
    persons
  • Science refers to these as embryos (no longer
    using pre-embryo)
  • Biology texts confirm the continuum between
    embryo, fetus, child, adult
  • Slippery slope
  • Uniqueness of each embryonic life
  • Principle of do no harm

14
The Ethics of Embryonic Stem Cell Research
  • The Case for using embryos
  • There are numerous embryos available that will
    otherwise be destroyed
  • Better to use these for potential good than
    simply discard them
  • Embryos are not considered human until
    implantation
