Blood is drawn from the arm (just like when you have a blood test done). Using a specialized centrifuge, the technician will separate stem cells and growth factors from the red and white blood cells. The platelets are transferred into another tube where a few drops of calcium chloride solution trick the platelets into thinking that they are in the body and the body has been injured.
