There are no known negative effects of autologous cellular therapy besides pain from where the tissue is harvested, a one percent chance of infection and of local bruising. Since we are using your body’s own tissue, the implanted cells are not rejected. There is also a chance that the procedure won’t work for the intended result (you might still have pain).
When implanting cells from another human (allograft therapy), there is a potential downside of rejection, but the percentage chance of this happening is not known. There is also a chance that the procedure won’t work for the intended result (you might still have pain).
With birth products, there is a chance of transmitting an infection, an immune reaction to the transplanted tissue, as well as pain and inflammation. The recipient’s body may attack the transplanted tissue because they are foreign. This is why we encourage the use of the patient’s own cells, rather than using tissue from others.
