We would like to thank Dr Klein for his insightful and, as always, thought-provoking comments. It is true that there has historically been a lack of consensus among physicians as to whether autologous fat cells survive freezing and are therefore useful for transplantation. There are also physicians who question whether autologous fat transplantation (AFT) works as anything other than a temporary filler substance, whether fat cells actually survive (fresh or frozen), or whether postsurgical fibrosis is the true mechanism of action.
