Questions & Answers
Q: What are stem cells and why are they important in regenerative medicine?
Stem cells are flexible cells that have the ability to differentiate into various tissues. They are valuable in regenerative medicine because they can potentially heal or replace damaged tissues in the body.
Q: Why have embryonic stem cell research faced ethical controversies?
Embryonic stem cells are derived from embryos, raising ethical concerns about the destruction of embryos for research purposes, even if it could potentially save lives.
Q: What are mesenchymal stem cells, and how do they differ from embryonic stem cells?
Mesenchymal stem cells are derived from adults, avoiding ethical controversies. While they are not as potent as embryonic stem cells, they still have the ability to differentiate into various tissues, making them valuable in regenerative medicine.
Q: How were stem cells discovered in menstrual fluid?
Scientists collected menstrual fluid in 2007 and isolated the cells for testing. The cells passed the tests for cloning ability and differentiation into other types of cells, confirming their identity as stem cells.
Q: What advantages do menstrual stem cells have over other sources of mesenchymal stem cells?
Menstrual stem cells double much faster than those derived from bone marrow and other sources. They also demonstrate extensive plasticity, being able to differentiate into all nine different tissue types tested.
Summary & Key Takeaways
-
Stem cells are flexible cells that can differentiate into various tissues, making them valuable in regenerative medicine.
-
Embryonic stem cells, while highly potent, are ethically controversial and difficult to obtain.
-
Mesenchymal stem cells, derived from adults, are a more ethical alternative, but obtaining them is still invasive.
-
Menstrual fluid has been found to contain mesenchymal stem cells that show great potential for regenerative medicine, as they double faster and have extensive plasticity.
