Researchers from the University of Adelaide in Australia say this discovering could present new avenues for therapy and even reversal of the illness, and challenges the concept of osteoarthritis simply being a “wear and tear” situation.
According to Dr. Jia Ng, a postdoctoral researcher within the School of Medicine on the University of Adelaide and the co-lead creator of this examine, there was an enormous unmet want for the therapy of osteoarthritis.
“Most treatments for osteoarthritis concentrate on treating the symptoms and improving the quality of life instead of targeting the disease, which leads ultimately to joint replacement surgery — this inevitable prospect also has a significant impact on [a] patient’s mental health,” she defined to Medical News Today.
Dr. Ng stated you will need to present that osteoarthritis is not only the “wear and tear” situation many consider it to be:
“The original concept of osteoarthritis being a ‘wear and tear’ condition has an implication that the disease itself may not have pharmacological intervention to treat the disease and reverse the pathology. Wear and tear disease indicates that the progression of the disease is a matter of time and inevitable. By reimagining the disease, we provide an opportunity and more importantly, a pharmaceutical target for the medical community to discover new drugs to reverse and treat osteoarthritis.”
When potential causes for the development of osteoarthritis, Dr. Ng and her crew determined to take a look at stem cells.
“As a stem cell biologist, [I’ve] worked with a variety of stem cell populations throughout my career,” she defined. “The initiation of many diseases’ progression [has] been shown to be the consequence of a compromised stem cell population, such as blood cancer and colorectal cancers.“
“The question for me was then, why not osteoarthritis? All mature cells develop from a particular discrete source of stem cell population — if we can fix the source of mature cells, we can treat and reverse the impairment of all mature cells and tissues,” she added.

Scientists used a mouse mannequin of osteoarthritis and recognized a selected inhabitants of stem cells marked by the
“Grem1 gene is a family of bone morphogenic protein which has a role in regulating organogenesis, body patterning, and tissue differentiation,” Dr. Ng detailed. “Grem1 has also been shown to have roles in the intestine, bone marrow, pancreas, and brain. In the early stages of embryonic development, Grem1 is also involved in skeletogenesis — limb bud development. Hence, it was only natural to be curious about its role in skeletal diseases such as osteoarthritis.”
During the examine, researchers discovered therapy with fibroblast development issue 18 (FGF18) vitalized the speedy manufacturing of Grem1 cells within the joint cartilage of mice. This finally led to a big restoration of cartilage thickness and decreased osteoarthritis.
“We believe that our discovery of these cells would lead to therapeutic advancement to treat the disease and reverse the pathology,” Dr. Ng stated.
According to her, “[f]or the first time, we are providing pharmaceutical innovators a target for drug discovery. In fact, the proposed — not limited to — treatment FGF18 showed [an] indication of increased cartilage thickness post-treatment, a reverse of early pathology. This opens [the] door to other pharmaceutical options beyond FGF18.”
Dr. Ng stated the most important alternative she and her crew had by this analysis was to supply a goal for osteoarthritis remedies which have been proven to work.
“There have been others based on the concept of stimulating the cartilage cells —
“Phase 3 clinical trials in the U.S. [have] shown that using FGF18, a treatment that we have (shown) to target Grem1 cells, [has] extremely promising phase 2 results,” Dr. Ng added. “Similar drug discovery should aim for the same target to provide [a] better opportunity to reverse osteoarthritis pathology.”
MNT additionally spoke with Dr. Steve Yoon, physiatrist and director of The Regenerative Sports and Joint Clinic at Cedars-Sinai Kerlan-Jobe Institute in Los Angeles, not concerned within the analysis, about this examine.
“Anytime you see research being performed to try to help people with osteoarthritis, I think it’s, it’s always encouraging and promising,” he advised us. “This type of research is essential — the next step is to continue understanding the mechanisms at play here and how it will affect humans.”
“Researchers are trying to find ways to try to help people because [osteoarthritis] is a worldwide problem,” Dr. Yoon continued.
“It’s important to let people know that there’s some hope and that people are trying to find ways to cure, if you will, or reverse the degenerative effect that you get on joints. And to just encourage people that it’s worthwhile to do your best to try to maintain what you have in hopes that maybe there could be something coming down the pipeline in the future.”
