Reprogramming of a melanoma genome by nuclear transplantation.
We have used nuclear transplantation to test whether the reprogramming activity of oocytes can reestablish developmental pluripotency of malignant cancer cells. We show here that the nuclei of leukemia, lymphoma, and breast cancer cells could support normal preimplantation development to the blastocyst stage but failed to produce embryonic stem (ES) cells. However, a blastocyst cloned from a RA...
متن کاملNuclear transplantation: reprogramming of transplanted nuclei.
Recent results in animal cloning have demonstrated that the events of cell differentiation can be reversed. This reversal necessarily requires genetic reprogramming of the transplanted nucleus. It has emerged from review articles that synthesis of nuclear and ribosomal RNA is blocked after fusion independently of cell cycle stage of the transferred nucleus, and that the cytoplasm condition of 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 کاملReprogramming of melanoma cells by embryonic microenvironments.
In recent years, the reversion of the cancer phenotype of human melanoma cells in developing zebrafish and chick embryos has been reported. The aim of this review is to revise these and other related contributions regarding the regulation of embryonic cancer and to provide a framework with which to understand results from our laboratory on the interactions of human melanoma cells with post-impl...
متن کاملNuclear cloning and epigenetic reprogramming of the genome.
Cloning of mammals by nuclear transfer (NT) results in gestational or neonatal failure with at most a few percent of manipulated embryos resulting in live births. Many of those that survive to term succumb to a variety of abnormalities that are likely due to inappropriate epigenetic reprogramming. Cloned embryos derived from donors, such as embryonic stem cells, that may require little or no re...
