Stem Cell Injections ArizonaAbout R3 Stem Cell Centers of Excellence

R3 Stem Cell Centers of Excellence provide treatment options that bring people hope and pain relief. Hope that going under the knife can be avoided, and injury can be repaired  with the patient then being able do things like hike, swim, ride a bike, play with your kids again and be… Free of Pain!

Existing pain management therapies have been excellent at reducing pain by masking discomfort in a “band aid” fashion with medications such as cortisone, narcotics or anti-inflammatory medications.

These treatments work great for relief, but they do NOT repair the underlying problem!

Fixing Tissue Injury

So how is the problem actually fixed, whether it’s joint arthritis, neck or back pain, rotator cuff tendonitis, ligament injury, golfer’s or tennis elbow?

Regenerative Medicine at R3 Stem Cell has the potential for restoring normal anatomy by utilizing therapies with stem cells, platelet rich plasma therapy and growth factors to promote a healing response in your own body.

Stem Cells are akin to a blank slate and can change into several types of cells helpful for tissue regeneration depending on the environment in which they situated.
