Your own fat is rich in stem and regenerative cells, so simply performing fat transfer results in transfer of your own fatty tissue with stem cells.It is possible to remove the stem and regenerative cells from fat and inject them separately, but at the present time this process is forbidden in the US by the FDA. Many clinics, some not so reputable, advertise stem cell treatments when they are actually just doing fat transfer. Those that are separating the cells are quite possibly breaking the law.If you are getting the 'stem cells' as a filler or to add volume then there appears to be no real advantage for most people to separate the stem cells.There are non-cosmetic situations like arthritis and heart failure where studies are being carried out using separated and purified stem cells, but are still considered experimental in the US. A new clinic named Okyanos is opening shortly in the Bahamas that will legally be able to provide purified stem cell therapies, particularly for heart issues according to approved European protocols.
