Freiburg researchers transform skin cells into renal cells

A team of researchers from Freiburg has used direct programming to successfully produce kidney-like cells very similar to natural renal tubular cells in terms of appearance and function. These cells are thus a promising alternative to kidney cells isolated from animals and cells differentiated from embryonic stem cells. The reprogrammed kidney cells can be used, for example, for pharmacological and toxicological tests and investigating the…

DNA origami for decoding the language of biological cells

Cells have their own language that they use to communicate with each other. They need this language to be able to form intact tissues and fulfil their specific functions in the body. If these signalling pathways are disrupted, metabolic processes will suffer and result in diseases. We know many “words” of the cellular language, i.e. signalling molecules that bind to specific surface receptors and thereby trigger chemical reactions inside the…

Epigenetics – heritable traits without changing the DNA sequence

Epigenetics, i.e. the inheritance of traits that does not involve a change in the DNA sequence, was once a controversial subject that has since become a central focus of biological research. Epigenetic inheritance is now studied by numerous national and international research programmes. Many cellular regulatory and differentiation processes are controlled by epigenetic mechanisms that take place on different levels, including the DNA, histone,…

Inhibition of bromodomain affects stem cell differentiation

DNA methylation and histone modification are epigenetic mechanisms that affect gene transcription. Moreover, protein complexes can regulate gene expression by modifying chromatin structure and function. Dr. Thomas Günther and his team from the Center for Clinical Research at the Freiburg University Medical Center are studying the effect of the inhibitor PFI-3 on the BAF complex. This protein complex modifies chromatin structure and controls the…

DNA capture molecules wanted for cells

Artificial blood vessels made of special polymers are no longer a pipedream. However, one problem that needs to be solved is that the artificial vessels have to be compatible with tissue. One solution could be to dupe the body into thinking that the artificial vessels are real by coating their inside walls with the patient’s own cells. Researchers from Reutlingen have developed a microfluidic chip that identifies molecules that can capture the…

The first major cell migration

It is of crucial importance that cells stick tightly together where their function requires them to do so for example in organs such as the heart and the liver to name but two examples. However it is equally crucial that cells start to migrate at some stage during embryonic development in order to form such organs. Prof. Dr. Wolfgang Driever from the Institute of Biology I at the University of Freiburg and his team have elucidated the molecular…

MicroRNAs – the saviours of stem cells

Life means almost permanent renewal. Layers of skin and the blood cells of animals are replenished on a life-long basis while plants can even grow whole new leaves flowers and branches. All this is due to stem cells the all-rounders of the cell kingdom. In plants and animals stem cells have the potential to give rise to many types of cells thereby giving plants the ability to grow throughout their life cycle. But how does a cell know that it is a…

MTS: Shock wave technology for the therapy of diabetic foot ulcer

Almost 15 percent of an estimated seven million diabetes mellitus patients in Germany suffer from diabetic foot syndrome DFS. It is associated with damage to the foot nerves and blood vessels as well as the presence of chronic wounds which in thousands of cases every year precede lower leg amputations. The Konstanz-based company MTS Medical has developed a shock wave therapy system that has the potential to considerably reduce the number of…

Cadherins and Wnt signals – cell adhesion or growth and dispersion?

The proteins of the cadherin family form a kind of molecular zip that binds cells closely together thereby preventing cancer cells from migrating for example. Prof. Dr. Doris Wedlich and her team from the Karlsruhe Institute of Technology KIT were involved in the discovery that cadherins are not only involved in cell adhesion but also have other functions.

More than just waste removers

Cells need to get rid of misfolded proteins as quickly as possible, something that for a long time has appeared to be the major function of the enzyme ubiquitin and other similarly structured proteins. It has since become clear that ubiquitin and ubiquitin-like proteins also interfere considerably with the signalling networks of cells. Dr. Klaus-Peter Knobeloch and his colleagues at the Freiburg Neurocentre are investigating the molecular…

In recognition of the growing importance of angiogenesis research in the field of oncology the German Research Foundation has established two new research consortia as part of its Angiogenesis research priority programme one project focuses on the mechanisms of vascular differentiation and the second on the interaction between tumour cells and cells of the vascular wall which are prerequisites for tumour growth and metastasis.

There are only a few signalling pathways that have been as well conserved during evolution as the Notch signalling pathway. This is due to the pathways unique biological function. Notch enables two identical cells to develop into completely different tissues. Anette Preiß professor at the University of Hohenheim has been working on the function of the Notch signalling pathway for almost 20 years.

For three days from 9 to 11 October more than 300 scientists from over 20 countries met at the Haus der Wirtschaft in Stuttgart to discuss the current state of research the latest product developments and therapies in regenerative medicine and stem cell research.
