Ultrasonic Harvest of Adipose Tissue for Cell Therapies

Tissue Engineering

Cell based therapies using autologous adipose tissue may represent the future of regenerative medicine. In the most basic and time tested form, mature adipocytes and small parcels of surrounding tissue are harvested by standard suction lipectomy and transplanted to another anatomic location. In recent years, the regenerative potential of adipose precursor cells that reside in adipose tissue has been demonstrated and holds promise for clinical reconstructive strategies. These adipose derived stem cells (ASC's) can be isolated from whole fat tissue or lipoaspirate. Also in recent years, the popularity of ultrasonic liposuction techniques has increased. Newer generation devices are able to apply energy in a more efficient and focused manner. Since ultrasonic liposuction devices rely on cavitation to extract adipose tissue, the viability and function of harvested cells has been questioned. Preliminary data from our laboratory suggests that high numbers of viable mature adipocytes and ASC's can be harvested by ultrasonic techniques. We hypothesize that ultrasonic fat extraction will yield cells equivalent in number and function to standard liposuction.
