Final answer:
The best way to eliminate rejection is to use cells from d) the patient for the transplant, known as an autograft, which avoids immune response due to recognition of tissue as 'self'. Blood relatives are often better matches for other types of grafts, but immunosuppression is necessary to prevent rejection.
Step-by-step explanation:
In order to best eliminate the chance for rejection, a tissue or organ should be made from cells obtained from d) the patient themself.
This is referred to as an autograft and significantly reduces the risk of immune rejection since the transplanted tissue is recognized as 'self' by the patient's immune system.
Organ rejection occurs when the recipient's immune system recognizes the transplanted organ or tissue as foreign and attacks it.
The rejection risk is lowest with autografts, while it is higher with allografts from a cadaver or a sibling, and even higher with xenografts from another species, such as a pig.
Matching donors and the use of immunosuppressive therapy are crucial when it comes to transplants other than autografts.
Blood relatives may be preferred as organ donors due to a better genetic match, which can reduce rejection risks. However, even with siblings, there is only about a 25% chance for a full HLA match.
Immunosuppression helps prevent rejection by weakening the immune response to the transplanted organ or tissue.
