Cartilage injuries are painfully inconvenient—not just because they hurt, but because cartilage stubbornly refuses to regenerate on its own. You bash your knee skiing or twist it during a spirited football match, and suddenly, you're facing chronic pain, reduced mobility, and potentially, osteoarthritis down the road. It's a surprisingly common problem, but effective solutions remain annoyingly elusive. Until now, perhaps.
Researchers at the University of Basel and University Hospital Basel have come up with a novel—and pleasingly weird—idea. Instead of attempting yet another disappointing patch-up job, they've decided to harvest cells from the patient's nasal septum—yes, your nose cartilage—to grow replacements. And according to their latest study, just published in Science Translational Medicine, it seems the approach works even better if you simply give these cells more time to mature in the lab.
To be clear, cartilage regeneration isn't new. For years, researchers have been cultivating cartilage cells in dishes, scaffolds, and bioreactors in laboratories around the world. The Basel team, led by Professors Ivan Martin, Andrea Barbero, and Dr. Marcus Mumme, has been specifically focused on nasal cartilage cells—because, as it turns out, nasal cells have some uniquely useful biological properties.
For starters, these nasal cartilage cells seem peculiarly good at dampening inflammation—a crucial benefit, given that chronic joint inflammation can speed the decline towards osteoarthritis. According to Professor Martin, “Nasal septum cartilage cells have particular characteristics that are ideally suited to cartilage regeneration,” which is reassuring, if slightly unexpected.
But this study wasn't just about nasal cartilage's inherent advantages—it was about timing. Researchers compared two groups of patients (98 people spread across clinics in four countries), all with cartilage injuries to their knees. Half received nasal-derived cartilage grafts matured in the lab for just two days, mirroring common practices. The other half got grafts matured for two weeks—enough time for the engineered cartilage to adopt characteristics more akin to natural joint tissue.
Over the following two years, researchers tracked outcomes meticulously through questionnaires and MRI scans. Both groups improved—so far, so reassuring—but the two-week maturation group didn't just get better quicker; they stayed better longer. Their cartilage grafts integrated more naturally, even improving the composition of surrounding tissues. The gains in functionality and quality of life weren’t subtle—they were substantial and persistent.
“The longer period of prior maturation is worthwhile,” explains co-lead author Anke Wixmerten, with admirable clarity. The extra maturation requires marginally more effort and expense but results in dramatically improved outcomes. In medical research, we love clear signals like these.
Another fascinating twist emerged when looking at the severity of cartilage injuries. The benefit of extended maturation wasn't equal across the board—it was particularly pronounced in patients with larger, trickier injuries. Even those who had previously tried and failed other treatments found success. As Professor Barbero put it, “It is noteworthy that patients with larger injuries benefit from cartilage grafts with longer prior maturation periods.”
Of course, it's worth acknowledging the limitations clearly stated by the authors themselves. “Our study did not include a direct comparison with current treatments,” cautions Professor Martin. Still, the self-reported outcomes were markedly superior to those typically seen with conventional approaches, suggesting that these nasal cartilage implants could soon represent an important improvement in treating chronic joint damage.
What’s next? The Basel team is already gearing up for two major clinical studies funded by the Swiss National Science Foundation and Horizon Europe. These will specifically target patellofemoral osteoarthritis—arthritis affecting the kneecap. Osteoarthritis remains a notoriously frustrating condition: chronic, painful, debilitating, and resistant to current interventions. If nasal cartilage grafts can make meaningful headway here, we might genuinely have something worth getting excited about.
It's a reminder that medical advances often arrive from unexpected places—even, perhaps, your own nose.
