Survival of fat transfer, transplant, injection, or grafting
Excellent question with no definitive answer. Depending on the study your review fat grafts will survive anywhere from an average of 30-50%. There are also schools of thought that believe few fat cells survive and the success is attributable to stem cells that are transferred along with the fat cells. Survival can depend on the age and health of the patient, donor site, method of harvest/processing/transfer, as well as post-oeprative care.
