Transcript of TOK Presentation - Stem Cell Therapy

Stem Cell Research Brooke Mower
Brandon Howard what is a stem cell? An undifferentiated biological cell of a multicellular organism that can divide through mitosis and differentiate into diverse specialized cell types and self-renew by producing more stem cells. 4 sources of hESCs the human embryo embryonic placenta amniotic fluid umbilical cord bioethical issues: Is preventing a human life worth furthering medical knowledge? To what extent can one moral view be prioritized
over another? the duty to prevent or alleviate suffering the duty to respect the value of human life Can we as a society balance both ethical "duties" equally? Must something be ethical in all possible situations to be accepted by society ? Is it possible for the potential advantages of stem cell research to outweigh the ethical implications of using hESCs? three properties of stem cells: capable of dividing and renewing themselves over long periods of time
unspecialized nature
give rise to specialized cell types principles of bioethics: maximizing benefits / minimizing harm: respect for persons / autonomy: reason based approach emotion based approach global view on stem cell therapy: national view on stem cell therapy: Scottsdale, Arizona local view on
stem cell therapy: personal views on stem cell therapy: variants of stem cells: human embryonic stem cells (hESCs): human somatic stem cells (hSSCs): induced pluripotent stem cells (iPSCs): works cited: "Frequently Asked Questions." Stem Cell Basics: Introduction [Stem Cell Information]. National Institutes of Health, 21 Apr. 2009. Web. 13 Feb. 2013. stem cell therapy is much more restrictive in the united states as opposed to the policies of other countries largely due to the controversy that surrounds this topic in politics there are various stem cell centers throughout arizona however on a personal level there are multiple doctors at these facilities that feel personally opposed to using hESCs When does life begin?

Breast milk and breast tissue provide pluripotent stem cells - without destroying embryos http://ow.ly/iUQis #stemcells @m_m_campbell
Treasure chest. Both breast tissue & milk appear to yield pluripotent stem cells. Amazing. http://ow.ly/iUQis #stemcells @LilaGraceRose
We see this over and over: it's ADULT stem cells providing the breakthroughs. Both effective and ethical: http://ow.ly/iLGIt @Donum_Vitae
The success of adult stem cells has been so great that there is no reason 4 embryonic stem cell research #GoodNews @gmanews7

leukemia could hit someone close to you a relatively rare undifferentiated cell found in many organs and undifferentiated cell found in many organs and differentiated tissues with a limited capacity for both self renewal (in the laboratory) and differentiation a type of pluripotent stem cell derived from the inner cell mass of the blastocyst (a preimplantation embryo of about 150 cells produced by cell division following fertilization) *pluripotent: having the ability to give rise to all of the various cell types in the body somatic cells (adult cells) reprogrammed to enter an embryonic stem cell-like state by being forced to express factors important by maintaining the "stemness" of embryonic stem cells "Religious Groups' Official Positions on Stem Cell Research."

& personal safety stem cell researcher helping others, compassion, financial security, & status maximizing benefits minimizing harm & respect for persons maximizing benefits minimizing harm conclusion: opinion: stem cell research's potential outweighs the negative ethical implications and should have more of a priority in the US Is it possible for potential medical stem cell treatment to outweigh the ethical implications of using hESCs? there is never going to be an absolute moral decision that satisfies all parties, but a general consensus must be made in order to maximize benefits and minimize harms for future generations
