I-12: Nuclear Reprogramming in Bovin Somatic Cell Nuclear Transfer
Somatic cell nuclear transfer (SCNT or cloning) returns a differentiated cell to a totipotent status; a process termed nuclear reprogramming. Reproductive cloning has potential applications in both agriculture and biomedicine, but is limited by low efficiency. To understand the deficiencies of nuclear reprogramming, our research has focused on both candidate genes and global gene expression pat...
متن کاملEpigenetic reprogramming by somatic cell nuclear transfer in primates.
We recently demonstrated that somatic cells from adult primates could be reprogrammed into a pluripotent state by somatic cell nuclear transfer. However, the low efficiency with donor cells from one monkey necessitated the need for large oocyte numbers. Here, we demonstrate nearly threefold higher blastocyst development and embryonic stem (ES) cell derivation rates with different nuclear donor ...
متن کاملReprogramming following somatic cell nuclear transfer in primates is dependent upon nuclear remodeling.
BACKGROUND Somatic cell nuclear transfer (SCNT) requires cytoplast-mediated reprogramming of the donor nucleus. Cytoplast factors such as maturation promoting factor are implicated based on their involvement in nuclear envelope breakdown (NEBD) and premature chromosome condensation (PCC). Given prior difficulties in SCNT in primates using conventional protocols, we hypothesized that the ability...
متن کاملEpigenetic reprogramming and nuclear transfer
Nuclear transfer, also referred to as cloning, attracted public attention when the first mammal, the sheep Dolly, was cloned from an adult cell. In this review, we highlight some of the milestones reached in the 50 years following the first nuclear transplantations in frogs. We also address the problems associated with nuclear transfer and provide an survey on current stem-cell technology. In t...
متن کاملHuman somatic cell nuclear transfer (cloning).
Within 2 years of the announced birth in 1997 of Dolly, the lamb cloned from the mam-mary cells of an adult ewe, research groups announced that they had cloned mice and calves by using differentiated somatic cells (1– 3). In the cloning technique used to produce Dolly, the nucleus of a somatic cell of the ewe was transferred to a sheep oocyte from which the nucleus had been removed, and the cel...
