Stem Cell Progeny for Skiing
Lube it up! We lube our bike chains. We lube our chainsaws. We lube our cars— more often as they get older. So why not lube our joints?
Joints are naturally lubricated with charged sugar molecules called hyaluronic acid and lubricin. These fluids permit the joints to be five times as slick as ice-on-ice. With aging or arthritis, the chemistry of our joints changes, affecting the lubrication, the surfaces, and the surrounding tissues. The uncomfortable sensations we patients and skiers feel are often caused by joint stiffness.
This stiffness can be decreased by multiple strategies. First, nutrition may matter. The natural supplements glucosamine and chondroitin are the building blocks of the joint lining cartilage matrix. Orally ingesting 1500mg to 3000mg of glucosamine a day has proved to affect the joint chemistry in positive ways by increasing matrix production, decreasing degradative enzymes that break down cartilage, reducing inflammation, and increasing the lubricant hyaluronic acid. (Injections of hyaluronic acid alone directly into the joint have had mixed results, with some patients doing extraordinarily well and others obtaining no benefit.)
Daily exercise increases blood flow to the joints, strengthens the surrounding muscles, and increases testosterone, pheromones, and adrenalin—all of which improve one’s sense of well-being and mobility.
Hydration with water—rather than with coffee, soft drinks, or alcohol—increases tissue elasticity. Dehydrated tissues are stiff, not stretchy.
Most excitingly; stem cell derivatives called progenitor cells and growth factors are playing an ever-increasing role in joint health. Stem-cell-derived self-repair cells called progenitor cells are growth factor engines. They help decrease inflammation, are anti-microbial, and stimulate more lubrication production, amongst many other positive attributes.
Fortunately, stem cells can be activated to divide and produce progenitor cells by certain growth factors and cytokines. When combined with injectable hyaluronic acid the lining of the joints can be stimulated to produce more natural lubricant.
At present, the only way to get these cells and growth factors into the joint is by injection; but like the vaccines that can now be given by needle-free vapor guns, these therapies may be delivered more easily in the future.
So, will we one day wax our skis and lube our joints before skiing? Someday, if the cost is low enough and the delivery method safe enough, we surely will lube before we slide...
