This is actually an area of research, "releasing" the locks of the epigenetic code and getting differentiated somatic cells to behave like pluripotent stem cells again, in order to use them to recreate damaged tissue. However, while that would be fine in a test.tube, it would be very bad if it happened inside the bodys existing differentiated tissue.
