I heard that for fat transfer procedures, if you retain the growth factors in the fat after removing it, it can then last forever once reinjected. Is this true? Can you explain this a bit more?
I have been performing fat transfer procedures for many years. My technique has not changed a great deal, but, like everything else, the more fat transfer procedures that I perform, the better I get at them and the longer the fat lasts with no distorted appearance. The whole discussion of growth factors and fat transfer has been truly distorted, and I feel that surgeons who are looking to market themselves as growth factors surgeons are the culprits behind all of this confusion. The claims that are made by these “growth factors” surgeons are preposterous. They are doing absolutely nothing novel with their techniques that have not been done before. Fat does contain growth factors. Brilliant scientists in laboratories dedicated to nothing but the study of growth factors have discovered this for us. Surgeons have done very little to add to our knowledge base of growth factors other than with anecdotal reports of increased cell longevity. Fat transfer is a technique with a steep learning curve. The results of the procedure are very rewarding for the patient and surgeon. I truly believe that at some point we will know more about the use of growth factors in fat transfer, but, at this point in time we still have a lot to learn.
