The Influence of Negative Pressure and of the Harvesting Site on the Characteristics of Human Adipose Tissue-Derived Stromal Cells from Lipoaspirates

Table 2

The viability of ADSCs. The viability of ADSCs harvested under low pressure and under high pressure from the inner thigh area, from the outer thigh area, and from the abdomen area on days 1, 3, and 7 in passage 2. No significant difference was observed between the outer thigh and the abdomen harvesting sites. The inner thigh region was not statistically compared to the outer thigh and abdomen regions due to the relatively small sample size.
