Paying the Toll in Nuclear Reprogramming
The ability to reverse lineage-committed cells toward pluripotent stem cells or to another cell type is one of the ultimate goals in regenerative medicine. We recently discovered that activation of innate immunity, through Toll-like receptor 3, is required during this conversion of cell fate by causing global changes in the expression and activity of epigenetic modifiers. Here we discuss, in a ...
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 کاملAutophagy: Paying Charon's Toll
Autophagy (literally self-eating) has diverse cytoprotective functions but also is linked to programmed cell death (PCD). In this issue, Qu et al. (2007) analyze the role of autophagy in PCD during development. Unexpectedly they find that autophagy induces apoptotic cells to present a signal to ensure their clearance, which is crucial for mouse embryonic morphogenesis.
متن کاملNuclear reprogramming.
There is currently particular interest in the field of nuclear reprogramming, a process by which the identity of specialised cells may be changed, typically to an embryonic-like state. Reprogramming procedures provide insight into many mechanisms of fundamental cell biology and have several promising applications, most notably in healthcare through the development of human disease models and pa...
متن کاملNuclear reprogramming in cells.
Nuclear reprogramming describes a switch in gene expression of one kind of cell to that of another unrelated cell type. Early studies in frog cloning provided some of the first experimental evidence for reprogramming. Subsequent procedures included mammalian somatic cell nuclear transfer, cell fusion, induction of pluripotency by ectopic gene expression, and direct reprogramming. Through these ...
