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.

Anaemia guidelines updated after 50 years
Professor Sant-Rayn Pasricha is the Acting Deputy Director at the Walter Eliza Hall Institute of Medical Research in Melbourne, Australia. He is also a clinical haematologist at the Royal Melbourne Hospital and the Peter MacCallum Cancer Centre. From a young age, Prof Pasricha dreamed of becoming a doctor and found joy in learning about the human body and how to care for patients. After completing medical school, he developed a passion for working in low and middle-income countries, which led him to spend time working in East Timor, India, and Central Australia with First Nations communities.

Benefits of prehabilitation ahead of surgery
Dr Matthew Wallen PhD, AES, AEP is a Senior Research Fellow in Cancer Survivorship, the Deputy Lead of the Cancer Survivorship Program, and a Senior Lecturer in Exercise Science and Clinical Exercise Physiology within the College of Nursing and Health Sciences at Flinders University, in South Australia. His clinical interest focuses on improving outcomes for people requiring major surgery, specifically (1) lifestyle interventions, including exercise, nutritional, and psychological support to improve the health and wellbeing of people prior to surgery, termed ‘prehabilitation’, (2) novel physical function assessments aimed at identifying people at risk of treatment-related complications, and (3) implementation of new models of care in cancer.
