Mitosis in human embryonic stem (hES) cell cytoplast cybrid following fusion. A, B, C, D: Increasing appearance in background of red fluorescence [octamer binding transcription factor-4 (Oct-4)] surrounded by ring of green fluorescence [tumour rejection antigen-2-39 (TRA-2-39)], with no nucleoli being present. Blue fluorescence: DAPI, showing the chromosome location. Original magnification x40.
Immune rejection problems could affect any one of us. This unique research shows that producing individual patient cell lines for our own future needs is now something we might all want to consider.
Somatic cell nuclear transfer (SCNT) forms the basis for obtaining patient specific stem cells and with the presence of reprogramming factors in human embryonic stem (hES) cells, a method for replacing the nuclei of hES cells by somatic cell nuclei has been widely sought.
Nick Strelchenko et al. based at the Reproductive Genetics Institute in Chicago, USA, has now developed an original technique resulting in the first evidence of the complete replacement of the nuclei of hES cells by nuclei of somatic cells. Their paper Reprogramming of human somatic cells by embryonic stem cell cytoplast is accepted and was published online by Reproductive BioMedicine Online, www.rbmonline.com/Article/2071 on 18 November 2005. The final article will also be published in print in the January 2006 issue of the journal.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
