title: Effect of targeted ovarian cancer therapy using amniotic fluid mesenchymal stem cells transfected with enhanced green fluorescent protein-human interleukin-2 in vivo.
abstract: The aim of the present study was to investigate the effect of using amniotic fluid mesenchymal stem cells (AF-MSCs) in targeted ovarian cancer therapy in vivo. AF-MSCs were isolated from human second trimester AF and a plasmid, enhanced green fluorescent protein‑human interleukin‑2 (pEGFP‑hIL‑2) was formed. The plasmid was stably transfected into the AF‑MSCs and the cells were intravenously injected into ovarian cancer nude mice models. Following stable transfection of the vector, tumor formation, and the expression and activity of hIL‑2 were investigated, and microscopic pathological examinations of the tumor were performed. It was found that AF‑MSCs exhibited high motility during migration in vivo, and the vector, pEGFP‑hIL‑2 can be stably transfected into AF‑MSCs. Following stable transfection, this type of stem cell is able to successfully transport the therapeutic gene, IL-2, migrate to the ovarian cancer tumor site to secrete the functional IL-2 and treat the tumor. Thus, AF-MSCs may serve as transporters for therapeutic genes targeting ovarian tumor sites and, therefore, be involved in the treatment of tumors.
