Adipose-derived stem cell isolation techniques flow chart cited from the second reference. The wide variance in the time, materials, and effort for obtaining ASCs via the Standard Isolation and our Rapid Isolation techniques is shown. A highly viable population of around 250,000 ASCs can be derived from 250 ml of blood/saline fraction of the liposuction waste in as little as 30 minutes, as compared to 8–10 hours to obtain ASCs using the traditional isolation method. SVF, stromal vascular fraction; ABAM, antibiotic/antimycotic; FBS, fetal bovine serum.
