Stem Cell Research
Transcript of Stem Cell Research
"The centerpiece of regenerative medicine"
What is a Stem Cell?
- Origin of all cells
- Capable of regeneration
Type Specific Stem Cells
- Neural Stem Cells
- Skin Stem Cells
- Hematopoietic (Blood Stem Cells)
General Stem Cells
- Fetal Stem Cells
Uses of Stem Cells
Spinal cord injury
Artificially combining DNA to produce unique individuals
Organ and limb generation
Organs can be grown in "organ scaffolding"
Possible limb generation
Unethical: Embryonic stem cells
The research does not respect the value of human life
Embryonic cells are cells with a potential for life
Obtaining stem cells from an embryo involves killing of the developing embryo
Human life begins at conception
Ethical vs Unethical
Why should we consider ethics?
The ethical Debate
Why should this be supported ethically?
Many argue stem cell research is unethical because of the use of human embryos.
However, there is much more to it than that.
We must consider a number of factors.
When does human life begin?
Cell differentiation and coordination low until day 16.
Early embryos do not mirror human life.
Use of cells before this period does not harm human life.
The moral status of human beings
There is a person providing these cells to research.
It is their decision to donate embryonic cells to the cause.
May be through infertility treatment, frozen embryos that will be discarded anyway, and more.
Embryonic cells are no longer the only option.
Induced pluripotent cells are stem cells created from adult cells.
Provides a safe alternative to embryonic cells at conception.

TriviA question 1
How many antigens must match between the donor and recipient for a transplant to be successful?
trivia question 2
What is the difference between embryonic stem cells and adult stem cells?
Thousands discarded daily; is it not better to use them for research?
Stem Cell Transplants
Retrieval from donor
Societal benefits vs. Suffering
Do embryos suffer?
Rejection of Transplanted Cells (GVHD)
Stem Cells Can be Harvested from:
What do we think?
How far is too far?
Why put another organism at a higher chance of health complications through their lifespan if it is not necessary?
