Abstract (original English)

Background aims Adipose-derived stem cells (ASCs) are considered to play a positive role in wound healing as evidenced by their increasing use in breast reconstructive procedures. After chemotherapy for breast cancer, poor soft tissue wound healing is a major problem. In the present study, the functional capabilities and recovery of ASCs after exposure to chemotherapeutic agent paclitaxel (PTX) using in vitro and ex vivo models were demonstrated. Methods Human ASCs were isolated from periumbilical fat tissue and treated with PTX at various concentrations. Adult Sprague-Dawley rats were given intravenous injections with PTX. Two and four weeks after the initial PTX treatment, ASCs were isolated from rat adipose tissue. Proliferation, cell viability, apoptosis and cell migration rates were measured by growth curves, MTT assays, flow cytometry and scratch assays. ASCs were cultured in derivative-specific differentiation media with or without PTX for 3 weeks. Adipogenic, osteogenic and endothelial differentiation levels were measured by quantitative reverse transcriptase polymerase chain reaction and histological staining. Results PTX induced apoptosis, decreased the proliferation and cell migration rates of ASCs and inhibited ASCs multipotent differentiation in both in vitro human ASC populations and ex vivo rat ASC populations with PTX treatment. Furthermore, after cessation of P
