Title: Stem Cell Research


1
Stem Cell Research
  • By "Doctors" Scott Cardona, Grant Granado, George
    Matarangas, Calix O'Hara, and Paul Siewierski

2
What are stem cells?
  • Stem cells are cells with the capability of
    developing into many different types of cells.
    They are produced in some organs to replace
    damaged tissue.
  • http//stemcells.nih.gov/info/basics/

3
Stem Cells, cont.
  • Stem cells differ from other cells in that they
    are unspecialized but can become many different
    types of cells with specialized functions.
  • http//stemcells.nih.gov/info/basics/basics1.asp

4
Types of Stem Cells
  • There are two main types of stem cells with one
    major difference between them
  •     1. Embryonic stem cells, from
    developing embryos
  •     2. Adult stem cells, from adult tissue
  • http//www.medicalnewstoday.com/info/stem_cell/

5
Types of Stem Cells, cont.
  • Adult stem cells can be taken from umbilical
    cords, placenta, fat from liposuction, and other
    tissue from the body. They can even be harvested
    from cadavers that are "fresh" enough.

    arch.html

6
Types of Stem Cells, cont.
  • Embryonic stem cells are taken from human embryos
    that are grown in vitro, but currently, they are
    more commonly used in research than actual
    treatment
  • http//www.aproundtable.org/tps30info/stemcellrese
    arch.html

7
Stem Cell Research and Treatment
  • The majority of stem cell research and treatment
    is conducted using adult stem cells. In fact,
    adult stem cell treatment has already helped
    thousands of people.
  • http//www.aproundtable.org/tps30info/stemcellrese
    arch.html

8
Stem Cell Research, cont.
  • Adult stem cell research is 20-30 years ahead of
    embryonic cell research because of the difficulty
    of embryonic cells developing outside of their
    usual environment.

World's first transplant of a whole organ grown
in lab
  • November 2008
  • Claudia Castillo
  • damaged windpipe
  • lower chance of rejection
  • http//www.dailyglobal.com/2008/11/worlds-first-tr

10
Pros
  • replace/repair damaged organs
  • Reduced risk of Transplantation
  • Serious medical conditions, like cancer and birth
    defects, are due to abnormal cell division and
    differentiation.

11
Pros cont.
  • Cardiovascular disease
  • stem cells that are injected into the circulation
    or directly into the injured heart tissue...

13
Pros cont.
  •  New studies indicate that it may be possible to
    direct the differentiation of stem cells to form
    insulin-producing cells ...

14
Pros cont.
  • ...that eventually could be used in
    transplantation therapy for persons with
    diabetes.
  • Scientists know that turning genes on and off is
    central to this process.

15
Pros cont.
  • 336 million people have diabetes
  •  1 in 10 adults (552 million) will have diabetes
    by 2030
  • Associated with 231,404 deaths
  • Deaths will double by 2030

16
Pros cont.
  • Human stem cells could also be used to test new
    drugs
  • Ethical dilemmas are largest challenges
    to increased funding/ large-scale use

17
Cons
  • Cons come from two areas
  • 1. Embryos being destroyed
  • Destroyed Embryos lt 100 cells
  • Some equate this to murder
  • Only applies to embryonic research

19
Cons cont.
  •  Embryos cont.
  • Proponents argue cells already available from
    in-vitro
  • No new cells destroyed 
  •  
  •  
  • http//www.allaboutpopularissues.org/pros-and-cons
    -of-stem-cell-research.htm

20
Cons cont.
  • 2. Medical Grounds
  • Mice with Parkinson's treated with stem cells
    died at 20 rate
  • -Suggests stem cells not viable treatment

http//www.allaboutpopularissues.org/pros-and-cons
-of-stem-cell-research.htm
21
Cons cont.
  • Medical cont.
  • Cells must
  • Create enough tissue
  • Differentiate into correct cells
  • Survive the translplant
  •  Function properly
  •  Avoid harming recipent
  •  Hard to achieve this
  •  
  •  
  •  
  • http//stemcells.nih.gov/info/basics/basics6.asp
  •  

22
Cons Cont.
  • Cells being frozen for in vitro. Later stem cells
    can be obtained from these.

Groups who Support Stem Cell Research
  • Americans for Cures Foundation- will improve
    life.
  • American Association for the Advancement of
    Science- increases knowledge of human body.
  • Canadian Stem Cell Network- new treatments.
  •  
  •  
  •  http//www.stemcellresources.org/who_orgs.html

24
Groups who support cont.
  • Coalition for the Advancement of Medical
    Research-  developing new medicines.
  •  Planned Parenthood- providing services for the
    public.
  • 72 of Americans support Stem Cell research.
  •

  •  http//www.stemcellresources.org/who_orgs.html

25
Why do groups support it?
  • Believe it is morally right 
  • Outweighs any destruction of embryos
  • Alternatively, Embryos not considered "human"
  • http//poq.oxfordjournals.org/content/68/1/131.ful
    l

26
Groups that are Opposed to Stem Cell Research
  • United States Conference of Catholic Bishops-
    considers murder
  • Christian Coalition- violation of human rights
  • Concerned Women for America- conservation of life
  • Southern Basptist Convention- goes against
    beliefs/ all life is sacred
  •  
  •  http//www.cc.org/
  •  http//urj.org/

27
Groups who don't support cont.
  • Union of American Hebrew Congregations (Reform)-
    requirement to use knowledge to heal others
    without hurting
  • Greek Orthodox Archdiocese of America-
    destruction of fetuses is considered abortion
  •  
  •

  •  http//urj.org/

28
Why do these groups oppose Stem Cell Research?
  • Generally contend it is destruction of human life
  • Consider Embryos "human"
  • Often routed in religious doctrne
  • Catholics, Jews, Protestants, Orthodox Christians

29
Church's View
  • The Catholic Church condemns stem cell research
    on embryonic cells.
  •     The embryo is, from conception, a human
    being.

Church's View contd.
  •    Taking the life of another human is murder and
    wrong.

Church's View contd.
  • The end does not justify the means.

32
Church's View contd.
  •     Even if the end result is to save lives, the
    sacrificing of            innocent human beings
    to do so is wrong.

Church's View contd  
  •  The Church does not oppose adult stem cell
    research.
  •     There is no loss of life in adult stem cell
