Researchers are testing cutting-edge therapies that use adult stem cells to regenerate joint cartilage and repair arthritis damage. Eventually, these treatments may reduce pain and help patients postpone joint replacements. Here’s how...

Imagine a future where doctors take stem cells from your own body, grow them into cartilage in a lab and reinsert them into a joint eroded by osteoarthritis.

Or a day when physicians help your body heal itself by luring stem cells to a worn joint, where they transform into joint cartilage.

Today, such osteoarthritis treatments are only a glimmer in the eyes of researchers, who are just beginning to learn how to harness stem cells to generate joint cartilage and control inflammation in laboratories.

But for the 27 million Americans with osteoarthritis, adult stem cell research could promise amazing new treatments. Experts hope one day – perhaps in your lifetime, if you’re 50 years old – to apply these therapies and alleviate or prevent arthritis in people, as well as postpone or reduce the need for joint replacement surgery.

That day is still years away. “We’re [nowhere near] being able to put orthopedic surgeons out of work on joint replacements,” says Mary Goldring, Ph.D., professor of cell and developmental biology at Weill Cornell Medical College and senior scientist at the Hospital for Special Surgery in New York.

Most studies in the U.S. are in embryonic stages and being conducted on animals.

“We need much more evidence and research before we could recommend that a patient get such a treatment,” says Farshid Guilak, Ph.D., Laszlo Ormandy Professor of Orthopedic Surgery and director of orthopedic research at Duke University Medical Center.

 Ageless Beauty: Anti-aging  cosmetic procedures  at any age

January 22, 2013

As we age, our bodies change and so do our expectations about how we look. Young adults are the top group for rhinoplasty,  breast augmentation and laser hair removal  since body proportions, facial imbalances and clear, smooth skin are their top priority. For those between 35-50, Botulinum Toxin Type A in the form ofBotox®,  Dysport® and Xeomin® is king. Women who have had children and are trying to age gracefully are getting Mommy Makeovers (which include breast surgery, tummy tuck  and liposuction) and using hi-techlaser, light and skin resurfacing techniques. The over 50 crowd wants to be competitive and are getting facelifts, brow lifts (forehead lifts) and eyelid surgery  earlier, rather than later, to get ahead of the aging process and for safer surgery. But that doesn’t mean the over 65 group isn’t growing – plastic surgery  for retirees (or non-retirees) has increased by almost 80% in 10 years.
