What is a potential benefit of using adult stem cells over embryonic stem cells?

• Higher differentiation potential

• Lower risk of immune rejection

• Easier to harvest

• More ethical concerns

Which type of stem cells are found in the bone marrow and can give rise to various blood cells?

• Totipotent stem cells

• Pluripotent stem cells

• Multipotent stem cells

• Unipotent stem cells

What is a major advantage of using induced pluripotent stem cells (iPSCs) in research?

• They are easier to obtain than adult stem cells

• They do not involve ethical issues related to embryos

• They have a higher differentiation potential than embryonic stem cells

• They are less expensive to produce
