In the original article, De Coppi et al. reported that amniotic fluid-derived stem cells could give rise to a variety of cell types of different lineages, including liver cells, bone-forming cells and neurons. Cattaneo and colleagues now question the evidence that these amniotic stem cells are able to produce differentiated cells with features of the neuronal lineage.
EuroStemCell coordinator Austin Smith, of the Wellcome Trust Centre for Stem Cell Research in Cambridge, says “this report emphasises the need for full and rigorous evaluation of stem cells before major claims are made. Scientists should be aware of the implications for patients' groups and wider political debates".
Stem cell biologist Ole Isacson, from Harvard Medical School, commends the editors of Nature Biotechnology for their decision to publish a challenge to high impact findings. “This [attitude]” Isacson says, “strengthens the basis of stem cell research. Discourse is an essential part of the scientific progress”. Report author Cattaneo adds, “this field remains open. We hope the discussion will continue, and look forward to hearing more about the potential of amniotic fluid-derived stem cells.”
Although the EuroStemCell project has completed its research programme, its renowned website (www.eurostemcell.org) will continue to promote discourse, discussion and debate around stem cell research when it relaunches next month.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
