Background
New regenerative treatments have emerged with the use of multipotent mesenchymal cells, with special interest in adipose-derived stem cells (ADSCs). In recent years, studies that have sought to identify possible quantitative or qualitative differences in ADSCs derived from different donor subcutaneous adipose tissue have shown divergent results making the determination of a preferential donor area still considered inconclusive.
Materials and Methods
The number of ADSCs present in the adipose tissue collected by liposuction was quantified between five different body areas from 17 women, by means of the CFU-F assay and to investigate possible qualitative differences in the ADSCs from these different areas by analyzing: cell surface markers, cell kinetics, action of the supernatant produced by ADSCs from different body areas on fibroblast migration and, finally, differences in the secretome present in the supernatant produced by these cells.
Results
The highest mean concentration of CFU-Fs was the dorsum (23.20 ± 26.13), and the lowest was the thighs (6.87 ± 5.04). No qualitative differences were observed in the expression of the cell surface markers or in cell kinetics. Supernatants produced by the ADSCs derived from the abdomen and the thighs demonstrated an increased rate of migration of fibroblasts in vitro similarly. No differences were observed in the secretome between the ADSCs groups.
Conclusions
It was observed that the region of the dorsal upper back presented a greater number of ADSCs than the thighs. No qualitative differences were observed between the ADSCs of the five areas analyzed.
