Question

1.What types of diseases have the potential to be cured by stem cell technology?

2. Are any stem cell treatment currently approved or in clinical trials?

3. What is the difference between an embryonic stem cell and an adult stem cell? What are the changes that occur in a cell as itdifferentiates?

4. How are stem cells and cancer cells similar?

5. What are the ethical issues surrounding the use of embryonic stem cells? Can any of these issues be avoided using technology such as somatic cell transfer or induced pluripotent stem cells, explain why or why not?

6. What are the potential dangers of stem cell technology?

Can you help me with these questions? Thank you!

Explanation / Answer

1. stem cell technology is applied to regenerate the damaged tissues of various organs such as heart, skin, bone, spinal cord, liver, pancreas and cornea or to treat blood or any organ cancers. most known example is parkinson's disease.

2. currently approved stem cells trials are on certain bone, skin and corneal diseases which include tissue grafting. is has been proved to be safe in early stages.

3. The most major difference of embryonic stem cell is Pluripotency, that is ability to transform into any kind of cell type. Adult stem cells have limitations for differentiation in to a tissue of their own type.

4. The major similarity between stem cells and cancer cells is that they proliferate extensively. normal stem cells also have known to mediate oncogenesis.

5.Induced pluripotent stem cells can regulate the genes maintaining the embryonic stem cells. Induced pluripotent stem cells provide a non-controversial strategy unlike the production of embryonic stem cells. as it can be used to generate patient-specific stem cell lines.

6. potential risks associate with stem cell technology relate to Graft-versus-host disease, grafting failure, Organ damage, Infections, Cataracts, Infertility, arise of New cancers. it may also be related to other symptoms such as body, muscle, limb pain, vomiting, jundice or skin rashes.
