| 摘要 |
<p>The present invention relates to a method of minimizing immunological rejection of a nuclear transfer ('NT') fetus which includes transferring a NT embryo into an embryo recipient under conditions effective for development of a NT fetus with minimal risk of immunological rejection of the fetus due to a maternal anti-fetal MHC-I immune response. After determining an MHC-I antigen type for a NT embryo and an MHC-I antigen type for embryo recipients, the NT embryo is either (i) transferred into a first embryo recipient having a compatible MHC-I antigen type under conditions effective for development of a NT fetus from the NT embryo, or (ii) transferred into a second embryo recipient having an incompatible MHC-I antigen type, followed by regulating MHC-I expression of the NT embryo or suppressing an immune response of the embryo recipient under conditions effective for development of a nuclear transfer fetus.</p> |
