The Power to Heal Comes from Within

Powerful chemical weapons, also known as drugs, and sophisticated surgical procedures have dominated the practice of medicine for many decades.  For at least the last 15 years, maverick researchers and physicians have been exploring biologic alternatives to drugs and surgery.  Instead of searching the world for a novel chemical compound or engineering a sleek surgical device, they have looked in an unusual place--inside the body itself.  Could it be possible that the power to heal comes from within our own bodies?  The answer today is a qualified yes.  

Think about it for just a moment.  Next time your get a small paper cut, simply observe what happens.  You bleed a little.  It stops on it own.  You put a bandaid on it and magically it heals over the course of less than a week.  Similarly, if you sustain a simple fracture, it typically heals on its own with immobilization and a few weeks of time.  Your liver is your most amazing regenerative organ.  You can literally cut out a lobe of your liver and transplant it into someone else.  That missing lobe will then regrow on its own.  Skin, bone and liver are tissues that have excellent capacity to self heal. Other tissues need a helping hand.  Fortunately, within our own bodies are many tissues that can help heal other tissues.  Blood, bone marrow and adipose tissue (also known as Fat) are three examples.

To begin, let's explore platelet rich plasma, also known as "PRP".  PRP is a component of blood that can be prepared using a simple desktop sized centrifuge in about 10 minutes.  I have using PRP to treat chronic tennis elbow now for more than a decade with excellent success rates.  Multiple studies now confirm the value of PRP in the treatment of this common disorder.  A recent meta-analysis of randomized controlled trials noted PRP to be "of great clinical significance."  PRP has also been used to treat diabetic foot ulcers, knee arthritis and degenerative disc disease.  Overall, there are now more than 8600 published studies evaluating the basic science and clinically efficacy of PRP.   Importantly, in all of the areas studied, PRP has an excellent safety record.  That of course makes sense.  PRP is simply a component of your own blood.

Cancer immunotherapy is another example of using your body to help heal itself.  Cancer immunotherapy essentially reprograms your immune system to help fight nasty cancers.  Recently published data has found an "unprecedented" 94% of patients with a specific type of blood cancer achieving complete resolution of their symptoms.  The technique involves removing your own white blood cells, reprogramming them to attack tumors in the lab and then injecting them back into your body.  To quote one researcher, "This is really a revolution."

Finally, a therapy that sounds like it came out of a science fiction or horror movie is just beginning.  The idea of parabiosis involves merging the circulation of two animals.  The original research was done in young and old rats in 1956.  For the details please review a tantalizing paper entitled "Experimental Prolongation of the Life Span (Ref 1)  When their circulations were connected, the young mice started becoming "old" and the old mice started to appear "young".  Something in the blood of young mice was helping reverse the affects of aging in older mice.  The coats of the old gray mice were turning brown again.  Other research conducted at Stanford suggested young blood could boost brain cell growth in older mice.  (Ref 2, Ref Ref 4)  This research was so intriguing, it led to the development of a clinical trial focused on the transfusion of young blood to older patients with Alzheimer's disease.   Silicon Valley tycoons are also helping finance similar "treatments" for middle aged rich people who want to stay young or reverse the affects of aging.  A company has even been started and is presently conducting clinical trials.  Interestingly, the company is named Ambrosia after the mythologic Greek drink that was supposed to confer longevity or even immortality.  Peter Thiel, an iconoclastic venture capitalist , appears to be quite interested in this approach to combating the aging process.  This approach is clearly not yet proven but is intriguing.

If we are seeking transformative solutions to difficult problems, I suggest we look inside.  We might just find the power to heal.
