Research interests:
-
Use of novel biomedical engineering strategies such as magnetic nanoparticles, nanopatterned surfaces and neural cell seeded polymer scaffolds to promote neural regeneration;
- Development of ex vivo tissue engineering models to evaluate the regeneration promoting effects of cell replacement;
-
Investigation of the molecular effects of immunotherapies on developmental myelin genesis and remyelination
We collaborate widely and currently use a combination of methods for these studies including:
- Isolated neural cell culture (primary cultures of neural stem cells, oligodendrocyte precursor cells, olfactory ensheathing cells, oligodendrocytes, astrocytes and neuronal cell lines)
- Microarray, proteomic and bioinformatics analysis of drug and magnetic nanoparticle treated neural cells for safety testing (with Dr Richard Emes, Director Advanced Data Analysis centre, Nottingham University; Dr Sarah Hart, Keele University.)
- Evaluating effects of nanoscale topography on neural stem cell proliferation and differentiation (with Dr Matt Dalby and Dr Nikolaaj Gaadegard, Glasgow University Centre for Cell Engineering).
- Development of in vitro neurological injury models in organotypic slice cultures, with electrophysiological recordings from regenerating nerve fibres (with Dr Michael Evans and Dr Stanislaw Glazewski, Keele University)
- TEM to monitor intracellular nanoparticle fate, and development of novel, high throughput and high resolution SEM methods to examine stem cell-nanomaterial interactions (with Dr David Furness, Director, Keele University Electron Microscopy Unit)
- Testing and characterising novel nanoparticles for labelling and gene delivery in stem cell transplant populations (with Dr Boris Polyak, Drexel University; Dr Humphrey Yiu, Heriot Watt University and Dr Vladimir Zholobenko, Keele University) used with state of the art static and oscillating field ‘magnetofection’ techniques
- Mathematical modelling of the handling of synthetic materials by neural cell populations (with Dr Theocharis Kyriacou, School of Computing Science and Mathematics, Keele University).
- In vivo models of CNS injury in the adult and neonatal brain and spinal cord (demyelination and transection) with cell transplantation
