Abstract

Today, adipose tissue derived mesenchymal stem cells (ADSC) have gained a great interest in various medical fields due to the characteristics of its self-renewal and multilineage differentiation capacity. The stromal vascular fraction (SVF) of adipose tissue is known to contain mesenchymal stem cells and it is obtained by processing the lipoaspirate which is usually collected from tumescent liposuction. In this study, we reviewed the records of patient epidemiology and results of SVF isolation. 30 patients (8 males and 22 females) had been underwent tumescent liposuction between April 2012 and January 2013, and the collected lipoaspirates were processed to isolate SVF in GMP facility in CHA Bundang Medical Center. The average stem cell count per 1 cc of lipoaspirate was 52,252 ± 26,704 and cell count including red blood cells per 1cc of lipoaspirate was 970,607 ± 873,436. The stem cell viability was proven to be 84 ± 4%. Bacteria were not detected in all the SVF samples. Compared to previous reports concerning the yield of SVF, our results coincide well with the results of previous studies. Because there were no domestic report about the yield and viability of SVF, this report may provide a reference value of the Korean SVF for the clinicians who want to use SVF as a therapeutic purpose.
