Stem cells obtained by nuclear transfer cause immune rejection

Genetic differences in the mitochondria of eggs used in the transfer of nuclei to obtain pluripotent stem cells trigger the process of immune rejection, but this is not the reason for rejecting the idea of using this method in the clinic.
