The benefits of injecting a high concentration of autologous platelets come from their release of growth factors and cytokines that can stimulate healing of a variety of tissues. All of the “good stuff” in platelets are encapsulated in granules, and so if an external source can increase the probability of degranulation, this effect can be enhanced. This same mechanism holds for other naturally occurring granules such as those in mast cells. But here is the tricky part. There are some instances where you do not want mast cells to degranulate (think of an allergic reaction) and others where you do (think of an open wound). It turns out that lasers have been shown to increase the local number of mast cells, but under certain circumstances these mast cells have been initiated to degranulate quicker, while other times not**.
While this may seem contradictory, it falls perfectly in line with some of the other secondary and tertiary effects of laser. Regulator proteins like bradykinin, prostaglandin, and even collagen do very different things when they are over or under expressed, and laser has been shown to promote BOTH over and under expression depending on the condition**. What? How?
Laser is the enabler. The local environment dictates which direction these mediators turn, not laser. Laser simply provides more fuel (oxygen to the area) and ignites the engine (forces the oxygen to be processed into ATP more efficiently). So whichever way the body is inclined to heal itself, laser will provide the boost.
It should be no surprise then, that the alpha granules inside platelets release their growth factors more readily when exposed to laser therapy. And while this seems very theoretical and abstract right now, with the number of practices utilizing these combinations (of laser with stem cell or PRP injections) ever increasing, the clinical data will start to fill in the gaps
