CASE STUDY
Filmed in Melbourne | March 2025
A landmark study led by WEHI and La Trobe University has found a potential new diagnostic marker that could be used to better detect the level of tissue damage in our bodies.
This study revealed, for the first time, a link between levels of EVs in the blood and tissue damage caused by diseases such as leukaemia.
Researchers hope to leverage the critical new insight to develop a blood test to monitor cancer patients with tissue damage, which could, in future, enhance treatment strategies for blood cancers and other diseases.
Extracellular vesicles (EVs) are like small delivery trucks in the human body that are dispatched by our cells to distribute important materials like proteins, fats and genetic information to other cells.
This delivery system helps cells communicate with each other, especially when they are under stress or dying.
Research into how EVs form and their link to disease progression is challenging because of their small size, with most studies restricted to a ‘cells-in-a-dish’ approach.
In an unprecedented study, researchers were able to overcome this significant barrier by imaging live EVs inside the bone marrow of mice.
The study involved a significant collaboration with Professor Ivan Poon, Director of the La Trobe Research Centre for Extracellular Vesicles (RCEV) – the largest group of EV researchers in the Southern Hemisphere.
The WEHI research team is now assessing whether EVs can be used as a biomarker in acute myeloid leukemia (AML) patients. They hope to develop new tools and techniques that would allow clinicians to determine the impact of disease on healthy tissue, and assess the disease progression by analysing patient samples.
The study, published in Nature Communications Oct 2024, also involved collaborations with the University of Melbourne, The Florey, Olivia Newton-John Cancer Research Institute, Peter MacCallum Cancer Centre and Monash University.
The research was supported by the National Health and Medical Research Council, Australian Research Council, CASS Foundation, Jack Brockhoff Foundation, L’Oreal UNESCO For Women in Science, Victorian Cancer Agency, a Sir Clive McPherson Family Fellowship and a Rae Foundation grant.

Enhancing occupational therapy service provision with military veterans
Prof McKinstry was instrumental in the development of the occupational therapy course at the La Trobe University’s Bendigo campus and also the establishment of the Rural Health School.
Prof McKinstry’s research focus is on health workforce, particularly developing a sustainable rural health workforce through recruitment of rural students for health courses, innovative and flexible delivery of health courses, telehealth and emerging areas of practice for occupational therapists.

Environmental exposure to function of lung epithelial stem cell biology
Dr Clare Weeden has recently commenced as a Laboratory Head at WEHI in 2025, supported by the CSL Centenary Fellowship.
Dr Weeden specialises in lung epithelial cell biology in the context of homeostasis, inflammation, and lung cancer, particularly in people who don’t smoke. Her work endeavours to understand how past environmental exposures shape the responses of lung cells and the molecular mechanisms underlying this cellular recall, with the aim to develop novel early detection strategies for lung disease.
