Abstract (original English)

Background Abdominal tissue enriched with adipose-derived stem cells (ASCs) is often used in cell-assisted lipotransfer procedures for breast reconstruction. However, as the tissue microenvironment and stem cell niche play important roles in defining the characteristics of the resident cells, it is hypothesized that the stem cell population present in the donor abdominal tissue has dissimilar properties as compared with the cells in the recipient breast tissue, which may ultimately affect the long-term success of the graft. Methods Adipose-derived stem cells were isolated from breast and abdominal fat tissues and characterized for mesenchymal-specific cell surface markers, and their population doubling, colony-forming capabilities, and proliferative properties were compared. The multilineage potential of both cell populations was also investigated. Results Adipose-derived stem cells from both tissue sites were found to possess similar marker expression and multilineage differentiation potential. However, breast fat-derived ASCs were observed to have a higher self-renewal capability and an unstable population doubling as compared with abdominal fat-derived ASCs. Gene expression studies revealed that the breast fat-derived ASCs were predisposed to the osteogenic lineage and the abdominal fat-derived ASCs to the adipogenic lineage. Conclusions Cells derived from both fat tissues p
