What does "multipotent" mean?

• able to divide and make one kind of cell
• able to divide and make all different types of cells
• able to divide and make multiple (but not all) types of cells 
• cannot divide

What is a benefit of using the patient's own stem cells to treat cancer?

• Your own stem cells won’t cause rejection as they’re taken from the patient themselves

• Your own stem cells have to be extracted from the bone marrow which is very painful

• Adult stem cells can only differentiate into a few cell types

• There is a risk of cancer returning
