The OAR proposal uses a variation of therapeutic cloning called altered nuclear transfer (ANT) in which the nucleus of a donor cell (a skin cell, for example), containing the 30,000 genes of the genetic code, is altered in such a way that it produces an epigenetic factor, a protein called nanog.
As specialized cells are generated during embryonic development, they are programmed to use only a limited amount of the total genetic information present in the nucleus to produce the proteins required for their particular function.

The prize will be equally split between biophysicist Venkatraman Ramakrishnan of the MRC Laboratory of Molecular Biology in Cambridge in England, biochemist Thomas Steitz of Yale University and molecular biologist Ada Yonath of the Weizmann Institute of Science in Rehovot, Israel, for their work in using x-ray crystallography to get a precise, atomic - scale map of the ribosome — the protein - making machine in all cells with nuclei that makes life possible.
And while cytochalasin D might not be the actual agent scientists use to trigger bone formation in the clinic, Rubin's study shows that triggering actin transport into the nuclei of cells may be a good way to force mesenchymal stem cells to become bone cells.
Research shows that in Parkinson's disease a brainstem region called the pedunculopontine nucleus (PPN) develops changes in DNA found in mitochondria — the batteries of the cell — as they produce and store energy that cells can use.
«Using this elegant method, we can reveal that not all the incoming viral DNA enters the cell nucleus as originally expected, but a significant fraction remains in the cytosol, the fluids of the cytoplasm,» explains Greber.
Once a cluster of supervoxels has been identified as a cell nucleus, the computer uses that information to find the nucleus again in subsequent images.
Zhong Zhong and Hua Hua are the product of somatic cell nuclear transfer (SCNT), the technique used to create Dolly the sheep over 20 years ago, in which researchers remove the nucleus from an egg cell and replace it with another nucleus from differentiated body cells.
Using this marker, the green fluorescence of the nucleus increases progressively in cells in the growth phase and turns off after the division.
Luiz Da Silva and colleagues from the University of California at Berkeley has already succeeded in using the Livermore laser to observe 50 - nanometre features in the nuclei of dried rat sperm cells (Science, vol 258, p 269).
Salk scientists were able to selectively add fluorescent proteins to the nuclei of motor neurons (red) using cutting - edge genetic techniques to show how cells in the spinal cord synchronize many neurons at once to allow complex movements.
The Ostrer study used DNA from the nucleus of the cell in its analyses, and the Behar study used both nuclear and mitochondrial DNA (mtDNA); the latter comes from tiny bodies in the living cell that provide it with energy.
Dolly was cloned using the technique of «somatic cell nuclear transfer,» when a nucleus from an adult cell is transferred into an unfertilized egg that has had its nucleus removed, and is then shocked with electricity to start cell growth.
In 1996 researchers in Scotland used SCNT to transplant the nucleus of an adult sheep cell into an enucleated sheep egg, producing Dolly, the first cloned mammal.
In the early 1950s, Robert Briggs and Thomas King repeated Spemann's experiments using a species of leopard frog, Rana pipiens, first with a nucleus from young embryos (Briggs and King, 1952) then from older embryos (King and Briggs, 1954); both the younger and older implanted nuclei could still be reprogrammed by the enucleated host cell.
DAPI was used to stain the cell nuclei (colored blue) at a concentration of 1.43 µM for 1hour at room temperature
Each set of 2 - D images was used to calculate a 3 - D reconstruction of a cell detailing the changing chromatin formations in the nuclei.
Over the past two decades, researchers have used various AAVs as vehicles to transport specific genes into the nuclei of cells; once there, the genes can be expressed, or translated, from DNA into proteins.
Researchers studying genome and cell biology provide evidence that heterochromatin organizes large parts of the genome into specific regions of the nucleus using liquid - liquid phase separation, a mechanism well known in physics but whose importance for biology has only recently been revealed.
Abstract: Using a mulit - reflection time - of - flight mass spectrograph (MRTOF - MS) located after a gas cell coupled with the gas - filled recoil ion separator GARIS - II, the masses of several heavy nuclei have been directly and precisely measured.
For instance, a science teacher might get kids to use their bodily - kinesthetic abilities by having them perform a lesson, representing a virus or the nucleus of a cell.
