A, I X S cells have four more key genes, so the genetic information of I X S cells is different from that of muscle cells, and A is wrong;

B and D indicate that this process only differentiates into various cells and does not form individuals, so it does not reflect the totipotency of I- 10 s cells, and B is wrong;

The expression of key genes in C and D formed I-X S cells, which did not make the cell function tend to specialization and C error.

D. Autotransplantation was performed after I- 10s cells were induced to differentiate into the required organs, and there was no immune rejection, which improved the success rate of organ transplantation. D is correct.

Therefore, choose: d.
