Which transplant method would prevent the rejection of tissue after an organ transplant?
(1) using organs cloned from the cells of the patient
(2) using organs produced by genetic engineering to get rid of all proteins in the donated organs
(3) using organs only from pigs or monkeys
(4) using an organ donated by a close relative because the proteins will always be identical to those of the recipient

The correct answer is (1) using organs cloned from the cells of the patient

Explanation:

Organ Cloning is a method to solve the failures/rejection in organ transplants. It consists of the creation of human embryonic stem cells in order to use them as raw material for different medical therapies. These can be used to produce a large number of different cells, including: tissues, muscles and organic cells. The main research in human organ cloning is aimed at achieving healthy tissues that can be transplanted in people without immunological rejection.
