The recognition that fat contains stem cells has driven further examination into the potential uses of fat and adipose-derived stem cells in a wide number of clinical situations. New information about the harvesting, isolation, and subsequent differentiation properties of isolated adipose-derived stem cells has led to new research into novel tissue-engineered constructs and the transformation of adipose-derived stem cells to induced pluripotent stem cells. Clinically, use of fat grafts and adipose-derived stem cells worldwide and in the United States has dramatically increased in parallel to questions concerning the safety and efficacy of adipose-derived stem cell–based treatments. Currently, the U.S. Food and Drug Administration has not approved the use of isolated adipose-derived stem cells for medical indications.
