Q. Consider the following statements regarding regenerative medicine:
1.Stem cell therapy involves manipulating cells in a lab to specialize into specific types like heart muscle or nerve cells before implantation.
2.During the process, chemotherapy may be used to intentionally wipe out the patient’s existing bone marrow to prepare for new stem cells.
3.Adult stem cells are preferred over embryonic ones because they can specialize into any cell type in the body without limitation.
Which of the statements given above is/are correct?
Answer: B
Notes:
Explanation:
- Statements 1 and 2 are correct: These are standard steps in stem cell therapy/transplants.
- Statement 3 is incorrect: It is Embryonic stem cells that are pluripotent (can become any cell type); adult stem cells are generally more limited in their specialization.
