Cell Therapy Imaging
Cell therapy could benefit many diseases. It comprises regenerative medicine, where cells repair areas of tissue damage, and cancer therapy, where cells are directed to recognise and kill cancer cells
Advancing cell-based therapies with cutting-edge imaging
Therapeutic cells are effectively a living drug that can migrate, proliferate, and in the case of stem cells, differentiate into numerous cell types, with the potential for tissue regeneration. It is vital that the efficacy of these therapies is assessed before they are applied to humans.
We are developing novel ways of tracking these cells throughout the body. We use nanoparticles and molecular imaging techniques to label the cells directly, or genetic engineering of the cells to produce unique biomolecules (proteins, receptors, transporters) that can be imaged both longitudinally and spatially.
We take a multi-modal approach for accessing cell distribution and cell fate over a range of imaging platforms (optical, photoacoustic, magnetic resonance and nuclear imaging) and across scales (whole body to cellular). Combining this with functional imaging of therapeutic response allows us to understand the complexity of this therapeutic approach with unrivalled precision. Through the knowledge of cell localisation, fate and therapeutic efficacy, we aim to move innovative therapies closer to a range of clinical applications.

Magnetic Targeting of Therapeutic Cells
Magnetic targeting has emerged as a method of improving the delivery and retention of transplanted therapeutic cells within a target organ. Magnetic nanoparticles such as superparamagnetic iron oxide nanoparticles (SPIONs), which become magnetic in the presence of a magnetic field, have been used to image and guide cells to sites of injury.
In CABI, we have pioneered the use of magnets as ways of steering labelled cells either by externally placed magnets or by utilizing the MRI scanner - a technique known as Magnetic Resonance Targeting (MRT). MRT was developed at CABI with Professor Quentin Pankhurst.
Reports demonstrate up to a 30-fold improvement in cell delivery and retention with a significant increase in therapeutic effect in some cases, suggesting that SPIONs are indeed an effective way of targeting cells.
Magnetic Actuation of Cells
The behaviour of cells can be influenced by magnetic particles in a process known as magnetic actuation. Magnetic particles can induce actuation via applying force to a cell (mechanotransduction), thermal stimulation (heating of the particle) or by the introduction of genes (magnetic transfection).
In regenerative medicine, magnetic actuation has the potential to control cell activation, differentiation, proliferation and migration of specific cell types enhancing their biological function.
At CABI we are exploring how manipulation cell phenotype and behaviour can be finely tuned utilising magnetic actuation and how this innovative field can provide important tools to realize the full potential of cell therapies.
