The incidence of end stage kidney disease is rising annually and it is now a
global public health problem. Current treatment options are dialysis or renal
transplantation, which apart from their significant drawbacks in terms of
increased morbidity and mortality, are placing an increasing economic burden on
society. Cell-based Regenerative Medicine Therapies (RMTs) have shown great
promise in rodent models of kidney disease, but clinical translation is hampered
due to the lack of adequate safety and efficacy data. Furthermore, the mechanisms
whereby the cell-based RMTs ameliorate injury are ill-defined. For instance, it
is not always clear if the cells directly replace damaged renal tissue, or
whether paracrine effects are more important. Knowledge of the mechanisms
responsible for the beneficial effects of cell therapies is crucial because it
could lead to the development of safer and more effective RMTs in the future. To
address these questions, novel in vivo imaging strategies are needed to monitor
the biodistribution of cell-based RMTs and evaluate their beneficial effects on
host tissues and organs, as well as any potential adverse effects. In this review
we will discuss how state-of-the-art imaging modalities, including
bioluminescence, magnetic resonance, nuclear imaging, ultrasound and an emerging
imaging technology called multispectral optoacoustic tomography, can be used in
combination with various imaging probes to track the fate and biodistribution of
cell-based RMTs in rodent models of kidney disease, and evaluate their effect on
renal function.
