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.

CASE STUDY Next Generation Condom Contraception
Eudaemon Technologies, an early-stage medtech company with a focus on sexual reproductive health, is developing a hydrogel condom to address the need for a better feeling, next generation condom, with the potential to improve user experience and address issues with traditional latex condoms.
“Over 1 million STI’s being diagnosed every day and up to 120 million unplanned pregnancies every year result in a $60 billion health burden across the globe”, says Co-Founder and Executive Director of Operations, Dr Simon Cook.
Formed in 2018, the company focuses on developing tough hydrogels as an alternative to address issues with odour, colour, and taste commonly associated with latex condoms. This technology can be loaded with small molecule drugs for flavours or anti-STI compounds, and was developed in response to a grant from the Bill and Melinda Gates Foundation to address unplanned pregnancies and STIs.

Identification & characterisation of molecular drivers of therapeutic resistance
Professor Pieter Eichhorn is an internationally experienced cancer biologist and research leader whose career has been defined by high-impact contributions at the interface of functional genomics, translational oncology, and research infrastructure strategy.
He completed his PhD at the University of Newcastle upon Tyne, contributing to the cloning of the gene associated with Cornelia de Lange Syndrome, before undertaking postdoctoral training at the Netherlands Cancer Institute in the laboratory of René Bernards. There, he performed pioneering functional genetic screens that identified key regulators of oncogenesis and therapy resistance, including critical roles for the PI3K signalling pathway in resistance to targeted breast cancer therapies.
