The reproductive system of this insect will be a model to understand stem cells better and make progress in their future use to treat certain human pathologies. The Andalusian Ministry of Innovation, Science and Enterprise has financed this project with 218,000 euros as part of their program of excellence.
Stem cells play an essential role in growth, as they allow the generation of different types of cells like neurones and egg cells, and the maintenance of adult tissues like blood, skin and the intestinal epithelium. In order to do so, it is necessary for stem cells to keep the potential that allows them to split almost unlimitedly and cause daughter cells that differ in different cell types.
In order to know more about stem cells, it is possible to test simple easy-to-study flies in a lab, like Drosophila melanogaster. This fly only has four chromosomes and its genome is already sequenced. Thanks to 80 years of study, we now know that many of the biological processes of Drosophila –despite the genetic simplicity of this fly- are very similar to vertebrates like mice and human beings.
This group of scientists have chosen to study fly’s ovary because, according to their leading researcher, Acaimo Gonzalez, ‘this organ is made up of just a few types of cells –including several types of stem cells- which allows us to identify stem cells unmistakably. Moreover, Drosophila allows us to make a genetic analysis of the biology of stem cells, which is essential for our research project’.
By analysing fly’s ovary, CABD’s scientists intend to show some light as to why a stem cell can split with the pass of time and remain indifferenced. Through the use of microarrays, scientists pursue to characterise those genes that are expressed in stem cells and study their function. According to Acaimo González, ‘it is essential to find out what genes are responsible for the maintenance of stem cells so that we can understand what stops stem cells from differentiating and keeps its proliferating potential unaffected’.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
