Abstract

In this study, we explored how the altered paracrine of adipose mesenchymal stem cells (ADSCs) contributed to the growth and cancer stem cell (CSC) properties of the Burkitt lymphoma cells. Condition mediums from normoxia or hypoxia cultured ADSC (CM-ADSC-N or CM-ADSC-H) were collected, and their effects on growth, colony formation, and apoptosis of Burkitt's lymphoma cells were investigated. Differentially expressed cytokines and inflammatory factors were compared between CM-ADSC-N and CM-ADSC-H. The involvement of differentially expressed IL-10 in growth and CSC properties of Burkitt lymphoma was investigated using both in vitro and in vivo models. Findings of this study showed that hypoxia increased IL-10 secretion from ADSCs, through which the growth and CSC properties of BL2 cells were enhanced. Intratumoral injection of CM-ADSC-H or IL-10 enhanced in vivo Burkitt lymphoma growth in nude mice model at least partly via the JAK2/STAT3 signaling pathway.
