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.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
So-called quantum many-body scars allow quantum systems to stay out of equilibrium much longer, explaining experiment | Study published in Nature Physics
Recently, researchers from Harvard and MIT succeeded in trapping a record 53 atoms and individually controlling their quantum state, realizing what is called a...
