Embryonic stem cells trigger immune rejection

Scientists from Stanford University in the States and Hannover Medical School in Germany have found that embryonic stem cells are rejected by the recipient's immune system after being implanted. Previously researchers have speculated about the possibility that embryonic stem cells may have an immune-privileged state, but new research shows that any future use of ESC is likely to require the use of systemic immunosuppression. This is a major disadvantage. Adult stem cells by contrast do not require immunosuppression if they are taken from the patient's own body.
