Meet the clinician-scientist mending broken hearts
It is always exciting to see researchers who we have backed in early careers progress, and their work blossom thanks to the generosity of our donors.
In this bulletin, we catch up with Sydney clinician and researcher James Chong, who is developing stem cell therapies to repair damaged heart tissue.
Support from our donors has helped James get his work to the point where he just won a $4.9 million grant from the Medical Research Future Fund (MRFF).
You can hear James speak about heart health and his research, and send in your own questions, through a webinar this month. Read on for more information.
We’re backing four more scientists working on treatments for cystic fibrosis, muscular dystrophy, and other diseases. Read on for more information and how you can join the effort to bring these treatments to clinical trials.
Later this year, we will publish a new patient information book for people considering stem cell therapies.
And early next year, we will help a group of students and early career researchers to attend Australia’s premier stem cell science conference – an investment in the next generation of medical scientists.
These are just some examples of how donations are making a difference.

Meet the stem cell scientist mending broken hearts
Cardiovascular disease is the leading cause of death for all Australians. Every year more than 57,000 Australians suffer a heart attack. Many develop heart failure.
Westmead Institute of Medical Research/University of Sydney scientist Associate Professor James Chong is pioneering the use of stem cells to repair heart damage. But further work is required before human clinical trials can safely commence.
With your help, we want to pump a further $100,000 into his heart research at the Westmead Institute of Medical Research through their ‘Double the Love’ campaign.
Donate now or any time through September until World Heart Day on 29 September, and we will match your donation dollar-for-dollar to double the impact.

James is sharing his research and heart health insights through a special online event on Wednesday 22 September at 1pm AEST.
James’ approach to heart repair is to inject stem cell-derived heart muscle cells or ‘cardiomyocytes’ directly into the injured region.
It has the potential to save the lives of millions of people as a viable alternative to heart transplants.
Compounding this, COVID-19 is being shown to impact heart health and the long-term consequences are unknown.

Early support leads to government funding success
We saw the promise of James’ work early. Following animal trials that featured in a landmark Nature paper, he received one of two $50,000 Metcalf Prizes from the National Stem Cell Foundation of Australia in 2016.
That helped him go on to prove that stem cells could repair the damaged hearts in other clinically relevant large animal models.
From there, James moved on to a five-year project aiming to bring to bring the therapy to a clinical trial with patients who have had heart attacks.
The Foundation swung behind him again with a Matched Funding initiative, under which we matched, dollar for dollar, every public donation of $500 or more.
Then this year, James was awarded $4.9 million by the Medical Research Future Fund 2020 Stem Cell Mission for his work which will allow clinical trials to go ahead.
James says the Matched Funding support was vital help in him winning the MRFF funding.
“It was really instrumental in helping me with this recent MRFF success,” he says.
“It allowed us to carry out the pre-clinical large animal work. Part of that was cell manufacture with my co-investigator in Queensland, Professor Peter Gray. And the large animal experiments have been instrumental in the preliminary data that I put into the MRFF grant application.”
James also has some other exciting news. The large animal large animal studies, while successful in repairing heart tissue, did in some cases cause an arrhythmia – a condition where the heart beats abnormally. Now he thinks he and his colleagues may have found a solution.
Being on the verge of publishing a paper on the subject, he can’t give too many details but says large animal studies have shown that the arrhythmia can be suppressed with a combination of two drugs, and that are already available in clinical use.
“So, it doesn't get rid of it totally, but suppresses it quite significantly, so that it becomes less sinister, less aggressive.”
Targeting new treatments for cystic fibrosis, muscular dystrophy, and other genetic diseases
Your chance to support research into therapies for inherited diseases
Each year, the Foundation selects up to four promising Australian stem cell research projects that need a funding boost to help them progress new therapies to human clinical trials.
As part of our Matched Funding Program, the Foundation will match money it receives from approved donors up to a maximum of $50,000, potentially providing a total of $100,000 for each project.
We are delighted to announce the 2021 Matched Funding Program recipients:
- Dr Peter Houweling from Murdoch Children's Research Institute is developing a treatment for a type of muscular dystrophy, a group of genetic diseases that cause progressive weakness and loss of muscle mass.
- Dr Gerard Kaiko from Hunter Medical Research Institute and the University of Newcastle is working on personalised gene therapy for the treatment of cystic fibrosis, an inherited condition that causes severe damage to the lungs, digestive system and other organs.
- Dr Raymond Wong from the Centre for Eye Research Australia and The University of Melbourne is developing a gene therapy for late-stage retinitis pigmentosa (RP), an inherited retinal disease that causes progressive loss of vision.
- Dr Sarah Withey from the Australian Institute for Bioengineering and Nanotechnology at the University of Queensland is using mini liver ‘organoids’ made from stem cells to test a treatment for children with a rare, genetic, progressive, life-limiting disease Ataxia Telangiectasia (A-T).
We will share more information about each project in future newsletters. In the meantime, we need donations to help us cover our half of the grants given to recipients.
Please consider assisting us in our work to support this important and growing area of medical science. The Foundation is registered as a Health Promotion Charity with the Australian Tax Office, so donations are tax deductible.
If you would like to make a donation or are considering making a bequest, please visit our website: www.stemcellfoundation.net.au/donate.
The 2022 funding round will open for applications early next year. For more information visit: www.stemcellfoundation.net.au/matched_funding_program.
