A Harvard-led team is the first to demonstrate the ability to use low-power light to trigger stem cells inside the body to regenerate tissue, an advance they reported in Science Translational Medicine. A number of biologically active molecules, such as regulatory proteins called growth factors, can trigger stem cells to differentiate into different cell types.
“Our treatment modality does not introduce anything new to the body, and lasers are routinely used in medicine and dentistry, so the barriers to clinical translation are low,” said Mooney, who is also the Robert P. Pinkas Family Professor of Bioengineering at Harvard’s School of Engineering and Applied Sciences (SEAS).
The FDA classifies our laser as an infrared heating device. Furthermore, the FDA states its use on humans as a “non-significant risk.” In plain English, that means no adverse effects. Lasers of this type have been used on over one million people in Europe, Asia and America for the last 50 years. To date there is not one documented adverse side effect from this technology. And, in the last decade, incredible technological advances have been made with these types of lasers.
Our laser pulses infrared light energy deep into your body, passing through those damaged cells. It is painless and non-invasive, and the deep heat actually feels very good. The damaged cells then absorb the infrared energy from the laser and begin to replicate a less damaged cell, and continues to do so — over and over. During our established and proven laser treatment protocols, which can last from 4 weeks to 8 weeks in duration, this process continues until the damaged cells consistently produce healthy cells. As the damaged nerve cells heal themselves, the pain greatly subsides or, in a very high percentage of people, goes away entirely. We all have what medical science calls “undifferentiated lymphocyte” cells within our bodies, which are essential natural stem cells. The laser passes the energy through these cells, and our immune system instructs these neutral cells to become what the body needs to begin the healing process. The human body and its ability to heal itself is simply incredible. After surgical procedures, it is the trauma to the body that signals the immune system to begin the healing process. The laser triggers this process without any further trauma to the body. Additionally, the laser’s energy increases the elasticity and the permeability of our cells. So what does that mean? Damaged cells often have excess edema fluid trapped around them. This excess fluid is what produces the swelling around a painful area. The energy from the laser causes our cells to allow absorption of this excess fluid, and our natural waste process removes it from the body. Therefore in many cases this effect brings immediate relief. While this process is taking place, the blood flow is increased to the painful area, bringing with it neutral stem cells to begin the healing process. The immune system is now in a heightened state instructing those neutral stem cells to become nerve, muscle, bone, skin cells or whatever the body determines it needs for its healing processes from this new energy source — our laser.
When you go outside, your skin cells absorb ultraviolet rays (UVB) from the sun. The sunlight triggers a form of cholesterol in our body called 7-dehydrocholesterol (7-DHC) to absorb the UVB rays. Our bodies absorb and metabolize this new energy, which prompts a series of reactions that lead to the production of a form of vitamin D, which is what our body uses to enable absorption of calcium and promote healthy bone development. So this is just one instance wherein light is transformed into a biological healing trigger. Every living thing on this planet depends on the energy of light from the sun for growth and survival. Plants, animals and a near endless number of biological processes all depend on the power of the sun. Even our mood is greatly influenced by sunshine. In fact, those who suffer from Seasonal Affective Disorder (SAD), which is a negative reaction to the changes of the seasons — light therapy is often utilized for treatment. People are generally more happy on sunny days than cloudy, dreary days. The sun has a verifiable effect on mood-related chemicals in our brain, so it is not surprising that it possesses other beneficial effects for our bodies.
