P-115: Melatonin Increases Developmental Rate of In Vitro Mouse Somatic Cell Nuclear
Background: The beneficial effect of supplementing culture medium with melatonin has been reported during in vitro embryo development of species such as mouse, bovine and porcine. However, the effect of melatonin on the mouse somatic cell nuclear transfer remained unknown. Materials and Methods: In this study, we assessed the effects of various concentrations of melatonin (10-6 to 10-12 M) on t...
متن کاملI-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 کاملP-86: Production of Cloned Mice by Somaticm Cell Nuclear Transfer
Background: For several years, mammalian cloning by splitting an early embryo or nuclear transfer into oocytes method has been successfully performed. Cloning is now also possible using adult somatic cells. Although it has now been 15 years since the first cloned mammals were generated from somatic cells using nuclear transfer (NT), the success rate for producing live offspring by cloning is lo...
متن کاملHuman somatic cell nuclear transfer and reproductive cloning: an Ethics Committee opinion.
This document presents arguments that conclude that it is unethical to use somatic cell nuclear transfer (SCNT) for infertility treatment due to concerns about safety; the unknown impact of SCNT on children, families, and society; and the availability of other ethically acceptable means of assisted reproduction. This document replaces the ASRM Ethics Committee report titled, "Human somatic cell...
