Question

Hematopoietic stem cell transplantation can be

• A. Autologous.
• B. Allogeneic.
• C. Syngeneic.
• D. All of the above.

Answer 1

The correct option is D All of the above.

Hematopoietic stem cells are obtained from the bone marrow and used for transplantation. There are different types of transplantations in which the donor from which the stem cells are received differs. In the case of the autologous stem cell transplantation, the stem cells are obtained from the same individual. In an allogeneic system, the stem cells can be obtained from any related or non-related person who is compatible with the patient. In the syngeneic stem cell transplantation, the stem cells are obtained from the identical twin.

Thus, the correct answer is option D.
