Stem cells are the body's 'master cells' that have not yet been programmed to perform a specific function. Most tissues have their own supply of stem cells, and it is becoming clear that if these cells can be given the appropriate biochemical instructions, they can 'differentiate' into new tissue. In this way, for example, stem cells could be seeded into damaged heart muscle to repair it.
Regenerative medicine has many advantages over more conventional ways of repairing or replacing damaged tissues or organs. Because the stem cells are taken from the person being treated, there are no problems with the body's immune system recognising the cells as 'foreign' and attempting to reject them, something that is still a problem with organ transplantation, for example.
To help ensure that Europe retains its competitive edge in the field, the ESF has launched REMEDIC, a research networking programme in regenerative medicine (13 May 2008). For the next five years a steering committee of 13 of Europe's leading specialists in regenerative medicine will organise a series of meetings and workshops to bring together experts to share ideas and develop new collaborations.
"I think this network will be very important to allow scientists in the field to share and disseminate information," says Professor Yrjö Konttinen, of Biomedicum Helsinki in Finland, who chairs the steering committee. "The network is open, so we will be in contact with many different organisations with an interest in the field. We want to meet people, establish joint collaborations with existing programmes and we will also be seeking funding for new initiatives."
REMEDIC will concentrate on the potential of a particular type of cell in the body called mesenchymal stromal cells. These can be obtained from fat tissue and coaxed to differentiate into a range of cell types, including bone, cartilage and muscle. Once the cells are in the relevant tissue, their growth and proliferation can be protected by biomaterials, which are structures implanted into the body that can guide the growth of the new tissue.
REMEDIC's first workshop is planned for mid-August in Helsinki, and a call for short term and exchange visits will be launched in late 2008. REMEDIC is a Research Networking Programme managed by the European Medical Research Councils (EMRC) at the European Science Foundation.

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.
Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....
The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
