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 کاملEfficiency of Ovine Fibroblast or Cumulus Cells For Somatic Cell Nuclear Transfer in Sheep
Purpose: Despite remarkable progresses have been achieved in the field of somatic cell nuclear transfer (SCNT), there is little information regarding the effect of donor cell type on the efficiency mammalian somatic cell cloning in vitro. This study compared in vitro developmental competency of sheep enucleated oocytes reconstructed with either fibroblast or cumulus cells. Material and methods...
متن کاملGeneration of bovine transgenics using somatic cell nuclear transfer
The ability to produce transgenic animals through the introduction of exogenous DNA has existed for many years. However, past methods available to generate transgenic animals, such as pronuclear microinjection or the use of embryonic stem cells, have either been inefficient or not available in all animals, bovine included. More recently somatic cell nuclear transfer has provided a method to cre...
متن کاملImproved efficiency of bovine cloning by autologous somatic cell nuclear transfer.
Somatic cell nuclear transfer (SCNT) has been used for the cloning of various mammals. However, the rates of successful, healthy birth are generally poor. To improve cloning efficiency, we report the utilization of an 'autologous SCNT' cloning technique in which the somatic nucleus of a female bovine donor is transferred to its own enucleated oocyte recovered by ovum pick up, in contrast to the...
متن کاملBovine and Swamp Buffalo Somatic Cell Nuclear Transfer in Thailand
This experiment was studied to examine the in vitro developmental potential of enucleateddomestic cat oocytes reconstructed with skin fibroblasts from female domestic and leopard cats. The cumulus oocyte complex of domestic cat were cultured in IVM medium under 38.5°C, 5%CO2, 5%O2,90%N2 for 24 hours. The matured oocytes were enucleated and individual donor cell was inserted into...
