Abstract (original English)

Background With recent research advances, adipose-derived stromal/stem cells (ASCs) have been demonstrated to facilitate the survival of fat grafts and thus are increasingly used for reconstructive procedures following surgery for breast cancer. Unfortunately, in patients, following radiation and chemotherapy for breast cancer suggest that these cancer treatment therapies may limit stem cell cellular functions important for soft tissue wound healing. For clinical translation to patients that have undergone cancer treatment, it is necessary to understand the effects of these therapies on the ASC's ability to improve fat graft survival in clinical practice. Aim To investigate whether the impact on ASCs function capacity and recovery in cancer patients may be due to the chemotherapy. Methods ASCs were isolated from the cancerous side and noncancerous side of the breast from the same patients with receiving neoadjuvant chemotherapy (NAC) or not-receiving NAC. ASCs were in vitro treated with 5-fluorouracil (5-FU), doxorubicin (DXR), and cyclophosphamide (Cytoxan) at various concentrations. The stem cells yield, cell viability, and proliferation rates were measured by growth curves and MTT assays. Differentiation capacity for adipogenesis was determined by qPCR analysis of the specific gene markers and histological staining. Results No significant differences were observed between th
