Which donor type refers to receiving one's own cells?

The donor type referring to receiving one's own cells is known as autologous. In tissue engineering and regenerative medicine, autologous cells are harvested from the same individual who will receive the treatment. This method has several advantages, including a lower risk of immune rejection since the cells are recognized by the body's immune system as self. Utilizing a patient’s own cells can enhance the compatibility and effectiveness of the treatment, as the cells are naturally adapted to the physiological environment of the patient’s body.

In contrast, allogeneic cells come from a donor of the same species but who is genetically different from the recipient. Xenogeneic refers to cells that are sourced from a different species altogether, which can introduce additional challenges related to immunocompatibility and ethical considerations. Additionally, the option "None of the above" does not apply since autologous is an accurate term for the described scenario. Therefore, autologous is the correct and appropriate term for receiving and using one’s own cells in medical procedures.
