Are all stem cells the same?

No, there are different types, such as embryonic stem cells (pluripotent), adult stem cells (multipotent or unipotent), and induced pluripotent stem cells (created in the lab).

What is a stem cell transplant used for?

It is primarily used to treat diseases of the blood and immune system, like leukaemia, by replacing damaged bone marrow with healthy stem cells.

Why are stem cells controversial?

Historically, the most potent (pluripotent) stem cells were derived from human embryos, raising significant ethical questions about the moral status of the embryo. This is less of an issue with adult or induced pluripotent stem cells.

Can stem cells turn into any cell?

Only pluripotent stem cells (like embryonic stem cells) have the potential to become any cell type in the body. Other stem cells are more limited in their potential.

Is “stem cell” formal?

Stem cell is usually formal, technical in register.
