Stem cells are the core unit of regenerative medicine. There are several sources of stem cells that can be used for treatment of the body. Internal stem cells come from inside your own body, while external sources come from outside the body. There are three sources of internal stem cells, however all are not useful/available to use for treatment. One source comes from adipose tissue; there are stem cells stored within body fat. Adipose stem cells are not mesenchymal and therefore not useful for treatment of damaged joints or disease conditions. Adipose tissue stem cells are used however in numerous cosmetic procedures. Another source of internal stem cells is bone marrow. While these are mesenchymal and could be useful for treatment, they must be harvested by a process called bone aspirate, a painful, invasive procedure requiring anesthesia, antibiotics, etc. Because of this, bone aspirate stem cells are generally not used for treatment. The best source of internal stem cells is called PRP (Platelet Rich Plasma). These are harvested by simply withdrawing a blood sample and separating the blood cells from the plasma. The plasma has a high concentration of mesenchymal stem cells and are quite useful in regenerative medicine. At Solutions Integrated Medicine, we offer PRP as one of the treatment options to our patients.
