UCSD team determines cellular stress within body is critical
...sponse pathway that is controlled by a gene called nuclear
factor of activated T cells 5 (NFAT5)/tonicity enhancer binding protein (TonEBP). This NFAT5/TonEBP protein is the only known mammalian transcription factor that is activated by hyperosmotic stress. Steffan N. Ho, M.D., Ph.D., a UCSD assistant profe...
Therapeutic cloning no longer a dream, says scientist who produced first cloned embryonic stem cell
...donors. Using the cloning technique somatic cell nuclear
transfer (SNCT), the researchers removed the nucleus of each unfertilised egg and replacing it with the nucleus taken from a cell from the cumulus the clump of cells that surrounds the egg - of the donor. The eggs were then stimulated to begin div...

transfer, a process colloquially known as "cloning." As part of the center, Feinberg and his colleagues will also implement a "minority action plan" to encourage racial and ethnic minorities to pursue education and careers in genetics and genomics. T...
Carnegie Mellon U. imaging study reveals sex-based differences that persist as mice enter adulthood
... internal structures. Both MRI and MRM make use of nuclear
magnetic resonance, a phenomena observed in the nuclei of atoms when they are exposed to a magnetic field and pulses of radio waves. MRM uses stronger magnets to capture images at a resolution 10-100 times finer than conventional MRI. Using MRM, Ahr...

Conflicting views on embryonic and adult stem cells complicate research in stem cell therapeutics
...however." It is possible to use a procedure called nuclear
transplantation to replace the DNA of an embryonic stem cell with DNA from one of the patient's own cells, eliminating the problem of immune rejection. In another approach, differentiating small numbers of ESCs into blood cells and injecting them int...
