Do you know anything or have an opinion on stem cells from liposuction fat?

My friend who is married to a right wingish sort of Libertarian doctor (the political persuasion actually matters to me in this instance, you will see why later) told me she had liposuction, then they take the fat, do something to it, and then give the stem cells back through an IV. I saw her the day she had it done, she told me she was going to look ten years younger. But, seriously, her biggest hope was that it would cure her Hashimotos disease (autoimmune hypothyroid) and make her healthier in general. Her husband had it done three weeks before.

I had not heard of this therapy, I just tried to google a little and a lot of things about creating blood vessels came up with this sort of stem cell, but I didn’t see anything that sounded like what she did.

She was telling me I should do it, and my response was, “I would be too afraid to try it until I know more and there has been years of it being done.” In fact, I asked her about the testing that has been done, and I don’t remember exactly what she said, but what stuck with me was that she said it is good to do it now before the FDA gets their hands on it and it becomes more expensive. As it is now it costs $8k. Meaning that is what her husband will be charging for the treatment. He is an orthopedic surgeon, and he believes this will be an alternative to having surgery and help in the healing process of people whodo have surgery.
