- Why are stem cells considered so valuable for medical research?
Becuase Stem Cells can transform into any cell of the body (plurypotent)
- Why did the researchers have to narrow the spectrum of genes within stem cells? (video 1)
Beacuase they needed to find an specific combinationon of genes that make this cell.
- What are the sources of stem cells and the advantages and disadvantages associated with using each?
The advantages: create any cell you need to regenerate an organ.
The disadvantages: to regenerate organs, you need to take stem cells from an embryo, which will die after.
- What are the three cases presented at the beginning of the second video?
A hockey player injured on his spinal cord; a man with diabetes; two little girls who had Tay-Sachs.
- How might a stem cell be used to treat spinal cord injuries?
Introduce them in the affected zone and then whait until it regenerates.
- Explain the outcome of the experiment with injured rats presented in the second video?
Some rats were used on the experimentation, they were handicapped, and after the treatment, they were able to walk, improving their life expectancy.
- What issues surround the debate over of stem cell research?
Some ethical issues, because killing an embryo for the beneffit of other people is very controversial, for example.
- What issue do you think needs to be debated as we make decisions about stem cell research?
To have the abbility of controling other people's life.
