Stem cells are undifferentiated cells found in the body. These "handymen" repair damaged tissues and maintain normal tissues. Stem cells help change the microenvironment of the injured tissue and activate a healing cascade, promoting anti-inflammation, inducing cell proliferation, as well as enhancing angiogenesis (the formation of new blood vessels) and other stem cell migration. These properties make them ideal for the treatment of arthritis, tendon, muscle, and ligament injuries.
SAC Regenerative Orthopaedics concentrates on two types of stem cells:
Your bone marrow contains both of these types of stem cells, along with endothelial progenitor cells which stimulate angiogenesis and release important compounds to grow tissue.
Additionally, bone marrow contains many growth factors and platelets that the body can use to promote healing. In contrast, adipose (fat) derived stem cells contain mesenchymal stem cells, but may not have many of the other contributing cells.
The concentration of stem cells in your bone marrow starts to decrease as you age. Although adipose tissue may not have some of the other contributing types of cells, age does not have an effect on the number of stem cells contained in fat. Dr. Panero will look at each individual and determine which harvest site is appropriate.
Bone marrow is aspirated from the back of your hip. This procedure is well tolerated because the back of your hip is precisely anesthetized under ultrasound guidance with a long acting anesthetic. Once the bone marrow is collected, it’s filtered through a machine, centrifuged and separated.
Fat’s collected from the belly, flank, or thigh. After receiving local anesthesia, the doctor inserts a thin tube to collect the adipose tissue, which is then put in a cylinder and “shaken.” Shaking separates the cells from the fat tissue and the stress of this agitation may activate them to start tissue repair.
Both procedures take 30 minutes and you go home the day of the procedure. Complete healing of bruising, swelling, and soreness will take about 1- 2 weeks.
