A team of researchers at the University of Glasgow and Heriot-Watt University, Edinburgh, have discovered a new way of blocking the spontaneous differentiation of stem cells by using the compound erythro-9-(2-hydroxy-3-nonyl)adenine (EHNA).
As explained by Peter Burton and colleagues in their paper published in the ChemBio Knowledge Environment of the Biochemical Journal, this means that human embryonic stem cells can be maintained in an undifferentiated state whilst remaining capable of differentiating to all cell types in the body, thus realizing their huge potential as research tools and for cell therapies.
Importantly, the EHNA treatment did not ‘lock’ the stem cells in an undifferentiated state, as the EHNA was removed, the cells were capable of multi-lineage differentiation.
The researchers note that EHNA is a robust, stable compound, readily prepared from commercially available starting materials at low cost in just two synthetic steps.
Bart Vanhaesebroeck, Deputy Chair for the BJ ChemBio Knowledge Environment, said: said “These findings have immense potential implications for bringing stem cell therapies closer to the clinic.”Full bibliographic information

Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale. In particular, the new method allows the imaging of quantum dots in a semiconductor chip. Together with colleagues from the University of Bochum, scientists from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute reported the findings in the journal Nature Photonics.
Microscopes allow us to see structures that are otherwise invisible to the human eye. However, conventional optical microscopes cannot be used to image...
On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
