People, they are not embryonic "baby" cells. The "baby" cells you all are referring to come from the afterbirth of a C Section with the mother's permission. In other words the umbilical cord and the placenta. They should not be called baby cells. Regenexx does not use these cells, they use only two types: your own bone marrow cells or your own fat cells. Using your own cells is inherently more safe. Regenexx seems to be reputable after some research. Be wary of the stem cell clinics popping up overnight with a stem cell shingle put out on their clinic. This procedure is not FDA approved or regulated. So in other words us consumers are taking a chance that the clinic we go to will actually know what they are doing, and how to place the cells. Us consumers could be getting a vial of water for thousands of dollars. I want to have stem cell treatment. But I am researching The Mayo Clinic to see what they offer. I want a reputable company that is knowledgeable and honest. I have arthritis in my ankle from a recent calcaneous break (broke my heel) and not arthritis from years of wear and tear. My foot is useless and painful. Does anyone know about the Mayo clinic and if they can help?
