According to the said researcher, this project “is part of the attempt that many laboratories are currently making worldwide to get to know better the biology of stem cells and the conditions in which some of their varieties could be used to treat some diseases”. In this case, scientists are going to study neural stem cells of adult mouse brains which, after being differentiated from neurons in a lab, will be implanted into the damaged cerebral cortex of genetically identical mice.
As Carmen Estrada explained, there is a specific area in the adult rodents’ brain, the subventricular area, where new neurons are massively generated from neural stem cells during the animals’ life. Although this phenomenon does not exist in humans in normal conditions, stem cells have been also detected in that area, with the possibility of generating new neurons under certain circumstances.
With this project, researchers will obtain information about neural stem cells that remain in the brain after birth, and will analyse their properties while they are in lab cultures, as well as after being implanted into the host brain.
Scientists hope to determine the conditions that allow neuron differentiation and to identify potentially useful genes as regulators or markers of such process. Thus, they will determine to what extent the neurons obtained in culture have the typical molecular structure of cells of its phenotype in adult brains.
In short, these trials will allow to establish “whether or not suitable neurons from neural stem cells can be transplanted into the brain of another animal”. The results will allow scientists to get to know the evolution of transplants and provide useful data in order to develop a cellular therapy as part of the treatment of some diseases linked to neuronal death.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
