Abstract:
BACKGROUND:Currently, cosmetic liposuction has developed rapidly, but the liposuction for the isolation of adipose-derived stem cells has not been reported.
OBJECTIVE:By evaluating the quantity and viability of stromal vascular fraction, adipocytes and adipose-derived stem cells obtained from different types of liposuctions, to find the advanced liposuction procedures that are most suitable for use in preparation, preservation and clinical application of adipose-derived stem cells.
METHODS:Authors retrieved PubMed database, NIH clinical trial databaseand CNKI ful text database for relevant articles using the key words of“adipose-derived stem cells, ADSCs, liposuction, SAL, UAL, PAL, WAL”in English and Chinese, respectively. After eliminating the objective-independent articles and repeating reviews, 50 papers were included for further analysis.
RESULTS AND CONCLUSION:Suction-assisted liposuction (SAL), ultrasound-assisted liposuction (UAL), power-assisted liposuction (PAL) and water-assisted liposuction (WAL) are four major types of fat-harvesting technologies that can possibly be applied for adipose-derived stem cells isolation. Accumulative evidence suggests that these advanced liposuctions can obtain high quality of adipose tissue/cells, which are good enough for autologous fat grafting. Adipose-derived stem cells that are isolated from lipoaspirate by WAL, SAL and UAL, can be used as autologous cel-assisted lipotransfer and regenerative therapy. In summary, although each of these four types of liposuction technologies has its own advantages and is feasible to be used as autologous fat grafting, systematic comparative studies for viability, chromosome stability and differentiation potentials of adipose-derived stem cells isolated using each col ecting method are necessary in order to confirm the future perspectives in adipose-derived stem cells isolation, banking and regenerative repair.
