stem cell technology Flashcards
What are stem cells?
Stem cells are undifferentiated cells that can develop into any type of tissue in the body.
Where can stem cells be harvested from?
Stem cells can be harvested from embryos (left over from IVF treatment), bone marrow, blood in the umbilical cord, and even skin and cartilage.
What are embryonic stem cells?
Embryonic stem cells are the most versatile stem cells, as they can develop into any tissue.
What are adult stem cells?
Adult stem cells are less controversial and are found in tissues like bone marrow. They are already used in treatments for conditions like leukaemia, and research is exploring their use for other treatments.
How are adult stem cells used in medical treatments?
Treating blood cancers like leukaemia through bone marrow transplants.
Replacing dead heart cells after a heart attack.
Growing skin tissue for burn victims.
Growing nerve cells for spinal cord injuries and Parkinson’s disease.
What is the future of stem cell treatments?
Many stem cell treatments are still being researched and perfected. While promising, further studies are needed to make these treatments effective and safe.
Can stem cells be collected for future use?
Yes, parents can collect umbilical cord blood at birth, which contains stem cells. This blood can be frozen and stored for potential future use, although it is an expensive option.
Why is stem cell research controversial?
Embryonic stem cell research is controversial because it involves destroying human embryos.
