The overall purpose of this study is to enhance identification and isolation of ADSCs and adipocytes, to find the optimum culturing conditions to increase growth and volume of grafts, and to study the effects of cryopreservation on ADSCs and adipocytes. Fat injections are used in aesthetic surgery but tend to disassemble over time. If the investigators can enhance growth and volume of fat in culture, the investigators could use fat grafts in reconstruction of cancer and traumatic injury defects with the patients own cultured fat cells and grafts.

Biospecimen Retention: Samples Without DNA
Other Outcome Measures:
- Percent of Necrotic ADSCs [ Time Frame: Day of Surgery ] [ Designated as safety issue: No ]
Percent of necrotic ADSCs will be measured on fresh samples and on refrigerated samples at 1, 2, 3, and 4 days of refrigerated storage.
Cells from lipoaspirate maximum of 20 days
