Dr Ralf Richter visited the University of Glasgow last Tuesday and delivered a talk at our weekly Biomaterials Seminar. He presented his work over the years with extracellular matrix polysaccharides and soft biological hydrogels, trying to understand how they function in health and disease.
Extracellular matrix polysaccharides such as hyaluronan (HA) and other glycosaminoglycans are vital to the communication of cells in multicellular organisms, and are involved in many physiological and pathological processes including inflammation, fertilization, neuronal plasticity, tumor development and atherosclerosis. How these molecules work remains largely elusive because they do not obey classical structure-function relationships and are challenging to study with conventional structural and biological techniques. They lack a well-defined secondary structure and much of their functions rely on the formation of dynamic and disordered supramolecular assemblies (hydrogel-like materials).
To study these molecules and materials, Richter’s lab has developed in vitro model systems with tunable complexity, like in vitro reconstituted HA matrices, or self-assembly of purified biomolecules on solid supports. These model systems are amenable to quantitative analysis, and allow a better understanding of how the properties of the individual molecules and interactions translate into supramolecular assemblies with distinct physico-chemical properties, and how new phenomena emerge from multivalent interactions. For instance with this models the Richter Lab have also shown that matrix-bound chemokines can promote cell adhesion even in the absence of any established cell adhesion ligand, and potentiate cell adhesion when such ligands are presented.
Dr Richter is a Associate Professor at University of Leeds. He has been to several European countries in his career. From his MSc in Sweden, PhD in France in 2004, to research done in Germany and Spain. More information on his research interests and projects can be found here.

The UofG Engineering Undergraduate Course and PhD information Event will take place this Wednesday 11th January in rooms 427A and B of the James Watt (South) Building. Doors open 3pm – 6pm. Several of our PhD students and Research Associates will be around. We have prepared two new posters that present the current research activity of MiMe.
Professors Matt Dalby and Manuel Salmeron-Sanchez will be giving a Joint Keynote Presentation titled “Working together – growth factor and nanovibrational technologies” this next Thursday 12th January at the 7th RSC Biomaterials Chemistry Special Interest Group Annual Conference at Ulster University, Northern Ireland. More info about the event here.
Prof Salmeron-Sanchez was interviewed on BBC Radio 4 and BBC World Service this morning. He talked about our recently awarded Find A Better Way grant. This is a five year long regenerative medicine project based in Glasgow to develop bone tissue grafts, grown in-vitro in the lab, ready to be delivered to the surgeon. The ultimate goal is to allow treatment of landmine and blast injuries and reconstruction of lost tissue beyond what is possible now.

A feature article has been published by Professors Manuel Salmerón-Sánchez and
The paper – Synergistic growth factor microenvironments. Chem. Commun., 2016, 52, 13327-13336 – is also accompanied by a contribution to the cover of ChemComm, Issue 91, 2016, thanks to the art skills of Dr. Aleixandre Rodrigo-Navarro.
The paper describes current advances with the presentation of growth factors (GF) bound to surfaces from a solid-phase state rather than in soluble form, recapitulating the way the extracellular matrix (ECM) binds GFs. This more effective presentation allows GFs to work in cooperation with integrins and enhance GF signalling due to the crosstalk between both receptors. This knowledge has been used to engineer microenvironments that target simultaneous integrin and GF receptor engagement seeking to maximise GF effects in vitro (e.g. in terms of stem cell differentiation) but also tissue repair in vivo (e.g. bone regeneration and wound healing).
