An experimental treatment for amyotrophic lateral sclerosis (Lou Gehrig's disease),which causes gradual loss of the ability to move,sends four genes into cells sampled from a patient's skin.This procedure reprograms the cells,which are then exposed to molecules and genes that stimulate them to develop as healthy versions of the cells affected in the disease.These cells are implanted into the patient.They are

The procedure described in the passage involves reprogramming cells taken from the patient's skin, which rules out options A and B. The use of four genes to reprogram the cells and the subsequent stimulation to develop as healthy versions of affected cells points to the use of induced pluripotent stem cells (option C) rather than apoptotic cells (option D), which would be dying or dead cells.
