Recent research at the University of Adelaide has led to a significant development in osteoarthritis treatment, indicating the possibility of reversing the condition. This innovative approach involves a new treatment that targets stem cells identified by the Gremlin 1 gene. The results from animal studies have been promising, and human trials are currently underway, following a successful five-year study period. This research is revolutionary, as it contradicts the traditional understanding of osteoarthritis and suggests a shift in how the condition could be treated.
Traditional treatments for osteoarthritis have primarily focused on alleviating symptoms rather than addressing the underlying cause. The University of Adelaide’s research, however, indicates that osteoarthritis might be both treatable and reversible.
Osteoarthritis is characterized by the deterioration of cartilage and adjacent joint tissues, and it’s the most prevalent form of arthritis in Australia. It affects 20% of individuals over the age of 45, significantly impacting their mobility. This long-term, progressive disease has been deemed incurable in the past, and in 2019-20, its treatment costs amounted to approximately $3.9 billion for the Australian health system.
Revolutionizing Research on Gremlin 1 Stem Cells
Traditionally categorized as a result of ‘wear and tear’, osteoarthritis can be exacerbated by factors such as aging, obesity, injury, and genetic predispositions. Researchers at the University of Adelaide identified a new group of stem cells, marked by the Gremlin 1 gene, which play a crucial role in the advancement of osteoarthritis.
Treatment with fibroblast growth factor 18 (FGF18) stimulated these Gremlin 1 cells in the joint cartilage of mice, leading to a notable restoration of cartilage thickness and a reduction in osteoarthritis symptoms. The discovery of Gremlin 1 cells opens new possibilities for regenerating cartilage and could be significant for other cartilage-related injuries and diseases, which are traditionally difficult to repair and treat.
Redefining Osteoarthritis Treatment
Dr. Jia Ng of the University of Adelaide’s Adelaide Medical School, who co-led the study, stated: “Our findings redefine osteoarthritis not just as a result of ‘wear and tear’ but as an active, reversible loss of vital articular cartilage stem cells. We are now exploring pharmaceutical solutions to directly target the stem cell population responsible for the development and progression of articular cartilage and osteoarthritis.”
Dr. Ng critiques current osteoarthritis treatments as merely superficial solutions. This new understanding, however, paves the way for pharmaceutical treatments that could potentially reverse osteoarthritis, improving health outcomes and quality of life for those affected by the disease. Dr. Ng also noted the association of osteoarthritis with other health conditions, including heart, pulmonary, and kidney diseases, mental and behavioral disorders, diabetes, and cancer.
Progress Towards Human Trials and Treatment Availability
While this research is currently limited to animal studies, Dr. Ng pointed out the genetic similarities with human samples and mentioned ongoing human trials. The results from a five-year clinical trial using FGF18 (Sprifermin) were published in 2021, showing promising long-term benefits without safety concerns. Phase 3 of the Sprifermin trial is in progress, and there is optimism about the public availability of this treatment in the near future.

Frequently Asked Questions (FAQs) about Osteoarthritis Treatment
What is the new breakthrough in osteoarthritis treatment?
A recent study from the University of Adelaide suggests that osteoarthritis may be treatable and reversible. This is based on a new treatment targeting stem cells marked by the Gremlin 1 gene. The treatment showed promising results in animal models, and human trials are underway.
How does the new osteoarthritis treatment work?
The treatment involves stimulating Gremlin 1 gene-marked stem cells. In animal models, specifically mice, this approach led to the recovery of cartilage thickness and a reduction in osteoarthritis symptoms. It represents a shift from symptom relief to addressing the root cause of osteoarthritis.
What makes this osteoarthritis research groundbreaking?
This research is groundbreaking as it challenges the traditional view of osteoarthritis as a non-reversible ‘wear and tear’ condition. The discovery of the role of Gremlin 1 gene-marked stem cells in cartilage regeneration and osteoarthritis progression opens new potential treatment avenues.
What are the implications of this osteoarthritis study for future treatments?
The study suggests that osteoarthritis might be reversible, and new pharmaceutical treatments could be developed to target the specific stem cells responsible for cartilage development and disease progression. This could lead to more effective treatments than current methods, which focus mainly on symptom management.
Are there any human trials for this new osteoarthritis treatment?
Yes, human trials are currently in progress. The research has moved from successful animal studies to human trials, following the encouraging results of a five-year study. These trials aim to confirm the efficacy and safety of the new treatment approach in humans.

great to see progress in medical research, this could be a game-changer for so many people!
Interesting study but i’m skeptical, how can a disease like osteoarthritis just be ‘reversed’? Seems too good to be true…
Wow this is huge news! can’t belive osteoarthritis might actually be reversible, really hope those human trials work out.
not sure how i feel about this, genetics and medicine is complicated stuff, and messing with genes? sounds risky.
