Research summary

Manipulating the stem cell niche to promote regeneration

Radiotherapy is a life-saving treatment for those with cancer; the majority of those with head and neck cancer will receive radiotherapy. Although radiotherapy, in the main, succeeds in treating the cancer, a severe side-effect is damage, including scarring or fibrosis, to healthy tissue. Cells which produce saliva can be destroyed, resulting in a multitude of oral problems, such as a difficulty in eating and speaking, all of which can adversely affect a patient’s quality of life. Existing treatments concentrate only on short-term relief of such side-effects. My group aim to develop a regenerative strategy to restore salivary function.

We have previously demonstrated that nerves surround the salivary glands and interact with stem cells, unspecialised cells that can develop into mature cells following injury, to promote regeneration. Importantly, both the gland and the nerves surrounding it are damaged by radiotherapy. My research group are working to develop technologies to mimic these nerve signals to control stem cells, inflammatory cells and senescent cells, to promote organ regeneration and greatly improve patient quality of life.

Current research interests

We have previously shown that cholinergic muscarinic signalling maintains SOX2+ progenitor cells in the SG. In collaboration with Dr. Asier Unciti-Broceta of IGC, we are testing the use of a novel technology to safely deliver a cholinergic drug to radiation-injured SG. This project aims to develop a completely new way of delivering a pharmacological therapy (based on neuronal signalling) to radiotherapy-injured SG without the typical systemic side-effects associated with cholinergic drugs. Macrophages are attractive therapeutic targets due to their unrivalled capacity to drive tissue repair and regeneration. We have used a suite of complementary approaches to map the heterogeneity of the salivary gland macrophage compartment throughout development and following radiotherapy injury . Furthermore, we have demonstrated an essential role for macrophages in the clearance of cells with DNA damage, as well as effective tissue repair following injury, absence of which leads to salivary gland dysfunction. Taken together, our data place macrophages at the heart of effective tissue repair following radiation-induced injury in the salivary gland and provide strong rationale for exploring the therapeutic potential of manipulating these cells to promote tissue repair. Using genetic lineage tracing we find that radiation injury alters SG macrophage replenishment kinetics, a phenomenon that parallels degeneration in SG architecture and function, which is suggestive of a failure of the supportive niche over time. Given that macrophages are considered to be in constant crosstalk with their structural neighbours, these data suggest that the effects of radiation may alter the SG niche so that it cannot support macrophage longevity/function; and conversely, that macrophages cannot support the SG niche. We are exploring the niche-derived factors that control SG macrophage maintenance and function, how these change in the context of SG injury, regeneration and degeneration and whether exogenous supplement can rescue this effect, and could ultimately provide new therapeutic avenues to target macrophages to promote tissue regeneration.
