  Purpose
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.

Condition

Study Type: Observational
Study Design: Observational Model: Case-Only

Primary Outcome Measures:
  • Percent of Viable ADSCs [ Time Frame: Day of Surgery ]
    Percent of viable ADSCs will be measured on fresh samples and samples refrigerated for different times.


Secondary Outcome Measures:
  • Percent of Apoptotic ADSCs [ Time Frame: Day of Surgery ]
    Percent of apoptotic ADSCs will be measured on fresh samples and on refrigerated samples at 1, 2, 3, and 4 days refrigerated storage.


Other Outcome Measures:
  • Percent of Necrotic ADSCs [ Time Frame: Day of Surgery ]
    Percent of necrotic ADSCs will be measured on fresh samples and on refrigerated samples at 1, 2, 3, and 4 days of refrigerated storage.
