Title: Stem Cell Research
1Stem Cell Research
- By "Doctors" Scott Cardona, Grant Granado, George
Matarangas, Calix O'Hara, and Paul Siewierski
2What 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/
3Stem 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
4Types 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

5Types 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. - http//www.aproundtable.org/tps30info/stemcellrese
arch.html
6Types 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
7Stem 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
8Stem 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. - http//www.aproundtable.org/tps30info/stemcellrese

9World's first transplant of a whole organ grown
in lab
- November 2008
- Claudia Castillo
- damaged windpipe
- lower chance of rejection

ansplant-of-a-whole-organ-grown-in-lab/
10Pros
- replace/repair damaged organs
- Reduced risk of Transplantation
- Serious medical conditions, like cancer and birth
defects, are due to abnormal cell division and
differentiation. - http//www.dailyglobal.com/200

central to this process. -

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

19Cons cont.
- Embryos cont.
- Proponents argue cells already available from
in-vitro - No new cells destroyed

http//www.allaboutpopularissues.org/pros-and-cons

- 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

-
-
-
- http//www.stemcellresources.org/who_orgs.html
25Why 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
26Groups 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/
27Groups 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//www.cc.org/
- http//urj.org/
28Why 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

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

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

- The Church does not oppose adult stem cell
research. - There is no loss of life in adult stem cell
