Effect of different choices and treatments with donor cells on repro-gramming
供体细胞的不同选择和处理对重编程过程的影响

Abstract: The donor nucleus must experienced the epigenetic modification of the process reprogramming and went back to the initial state after the donor cell was injected into the oocytes. If the reprogramming is not completed, the efficiency of cloning will be reduced. However, reprogramming of nucleus muct was not only embodied in its ability after it was trans-ferred into the oocytes. It was different in the potential if the cell type was not identical. In addition, different treatment to the donor cells resulted in different ability and the level of reprogramming. This paper described different effects of the type, algebra, cycles, age, and species of the donor cells after nuclear transplantation on the reprogramming. An overview of the exposition and analysis through the donor cell cryopreservation, serum starvation, and different reagent treatments were discussed.
