What are the pros and cons of using stem cells?
While stem cell therapy has the potential to cure many diseases and injuries, there are also some risks associated with this treatment. For example, there is a risk of rejection by the body’s immune system, as well as a risk of the stem cells turning into cancer cells.
What are the negative effects of stem cell research?

What can damage stem cells?
Several factors can contribute to the accumulation of DNA damage in stem cells of the adult organism, including telomere shortening, DNA replication stress and the failure of repair systems.
What are the disadvantages of stem cell preservation?
The lifetime probability of a baby using its own stored (banked) cord blood stem cells is less than 0.04% and hence this model is discouraged by medical bodies and stem cell transplantation experts in India and globally. Furthermore, cord blood from a single donor may not be sufficient for transplant in adults.
Is stem cell ethical or unethical?
Opponents argue that the research is unethical, because deriving the stem cells destroys the blastocyst, an unimplanted human embryo at the sixth to eighth day of development. As Bush declared when he vetoed last year’s stem cell bill, the federal government should not support “the taking of innocent human life.”
What are the cons of stem cells?
- Limitations on ASC ability to differentiate are still uncertain; currently thought to be multi or unipotent.
- Cannot be grown for long periods of time in culture.
- Usually a very small number in each tissue making them difficult to find and purify.
Are stem cells safe use?

Are stem cells good or not?
Stem cells are important for living organisms for many reasons. In the 3- to 5-day-old embryo, called a blastocyst, the inner cells give rise to the entire body of the organism, including all of the many specialized cell types and organs such as the heart, lung, skin, sperm, eggs and other tissues.
Is it OK to use stem cells?
