Now, because we have used so many platelets, the signal they send out is heard all over the body by a different subset of cells. Kind of like a construction crew…the plumbers, carpenters, electricians, bricklayers, painters, etc. They all have a specialty that is needed to construct a building. If we put a skeleton crew of construction workers at a job site, it takes quite a while for the job to be completed. Now if we increase the crew by tenfold, we hopefully can have our building up in a fraction of the time. The same is true with PRP and wound repair. Now imagine this. Our construction crew is driving to work and the bridge that they have to cross to get to the job site collapsed during the night. They can all crawl down the embankment and up the other side to get to work, but it is going to take a very long time for them to get to their destination and they are going to have to expend a lot of energy to accomplish this. The same thing happens when we are trying to repair a torn ligament or tendon, broken bone, diabetic wound or possibly a spinal fusion. To a cell, looking over torn ligament fibers is akin to looking over the Grand Canyon. They will probably never get from one side of the fiber to the other, so the injury remains chronic and eventually, some scar tissue will form, but the fibers never mend themselves.
