Transcript of Stem Cell Research

What is Stem Cell Research?
Dani Bowser, Audrey Troup, Sarah Lakhani, Shelby Fatherly, Kailey Tennant
Pros of Embryonic Stem Cell Research
Disadvantages of adult stem cells
Difficult to control growth-needs to be closely monitored
Multiply slowly
Could pass on diseases from animal sources
Pros of Adult Stem Cell Research
Stem Cell Research
Stem Cells are able to develop into a different cell type.
Example: Cells from extracted bone marrow are unspecified, so they can become muscle tissue, bone, or brain cell.
Creates specialized functions
Endless multiplication
Two types of Stem Cell Research:
Adult
Embryonic
Adult Stem Cells

Extracted from bone marrow
Donated from match
Human Leukocyte Antigens
Stem Cells--> Specialized Cells
Not Controversial
Extracted from adult donors not embryos
Disease Treatment
Examples:
Heart disease
Diabetes
Parkinson's disease
Cancer
Spinal Cord Injuries
Retinal diseases
Drug Testing
Induced Pluripotent
Stem Cells (iPSCs)
Where are adult stem cells located?
What's the Difference?
Diseases Benefited
Parkinson's
Alzheimer's
Heart Disease
Stroke's
Diabetes
iPSCs are reprogrammed to an embryonic stem cell–like state
Embryos-Intricate movements to shape a functional organism
divide infinitely
capable of specializing
Donated from IVF
Better treatment of these diseases could also give significant social benefits for individuals and economic gains for societ.
Cancer Treatment
Adult Stem Cell Age
Short lived-will not last in culture long.
Could develop more abnormalities in the DNA
Less flexibility and versatility-will stretch out
Researchers are continuing their research on cancer treatment but embryonic cells are playing a very big role in curing cancer.
Miscellaneous
How can they be used?
useful tools for drug development
modeling of diseases
scientists hope to use them in transplantation medicine
Birth Defects
Spinal Cord Injuries
Replace or Repair Damaged Organs
Reduced Risk of Transplantation (You could possibly get a copy of your own heart in a heart-transplantation in the future.

iPSCs can be used for testing drugs
Safer
More effective

Cons of Embryonic Stem Cells
Amounts of Cells collected
Small amounts
hard to locate and isolate
therapies need large numbers of cells
Ethical/Moral Reasons
destruction of blastocyst
life begins at conception
religion and God
Scientific and Monetary Issues
expensive
distinguishing pre embryo and embryo
tumors
untrustworthy
genetically defective
research on mice
FDA approval
