Rejection happens when the recipient's immune system attacks the transplanted tissues as it recognises them as foreign invaders.Why is rejection not a concern with transplants from a therapeutic clone?The transplanted cells are sterile because they have come from a lab, this means they would not trigger the immune system of the patient.The transplanted cells are a closer match to the patients own cells, which reduces the likelihood of rejection.The patient has been treated with medication to lower their immune system, this prevents immune rejection of the new cells.The transplanted cells are genetically identical to the patient, so they are the patient's cells and the immune system would not attack them as invaders.
