Abstract (original English)
Adipose-derived stem cells (ADSCs) are multipotent cells that have attracted much recent attention and emerged as therapeutic approaches in several medical fields. Although current knowledge of the biological impacts of ADSCs in cancer research is greatly improved, the underlying effects of ADSCs in tumor development remain controversial and cause the safety concerns in clinical utilization. Hence, we isolated primary ADSCs from the abdominal fat of mice and conducted interaction of ADSCs with Lewis lung carcinoma cells in culture and in mice to investigate the impacts of ADSCs on tumor development. Cytokine array and neutralizing antibody were further utilized to identify the key regulator and downstream signaling pathway. In this study, we demonstrated that ADSCs enhance the malignant characteristics of LLC1 cells, including cell growth ability and especially cancer stem cell property. ADSCs were then identified to promote tumor formation and growth in mice. We further determined that ADSC interaction with LLC1 cells stimulates increased secretion of interleukin-6 mainly from ADSCs, which then act in a paracrine manner on LLC1 cells to enhance their malignant characteristics. Interleukin-6 was also identified to regulate genes related to cell proliferation and cancer stem cell, as well as to activate JAK2/STAT3, a predominant interleukin-6-activated pathway, in LLC1 cells.
