BACKGROUND In tumor microenvironment, a continuous cross-talk between cancer cells and other cellular components is required to sustain tumor progression. Accumulating evidence suggests that exosomes, a novel way of cell communication, play an important role in such cross-talk. Exosomes could facilitate the direct intercellular transfer of proteins, lipids,(More)
Mesenchymal stem cells (MSCs) can be attracted to tumor sites and become an important component of the tumor microenvironment, thus contributing to tumor development. Emerging evidence suggests that tumor cells could transfer genetic information into MSCs through the release of exosomes. However, the molecular mechanisms by which tumor exosomes contribute(More)
BACKGROUND Considering promising results in animal models and patients, therapeutic use of MSCs for immune disease is likely to undergo continued evaluation. Low-lever laser (LLL) has been widely applied to retard the inflammatory reaction. LLL treatment can potentially be applied in anti-inflammatory therapy followed by stem cell therapy. AIM OF THE(More)
Chemokine stromal-derived factor-1 (SDF-1) and its receptor CXCR4 have been shown to play an important role in the migration and homing of the transplanted hematopoietic stem cells (HSCs). Mesenchymal stem cells (MSCs) express these molecules. This study is to test the hypothesis that acute myeloid leukemia (AML) alters the expression of SDF-1/CXCR4 in(More)
Mesenchymal stem cells (MSCs) have been proved to be an important element in cell-based therapy. Photobiomodulation used extremely low-level lasers (LLLs) to affect the behavior of cells. The effect mechanism of LLLs on MSCs from human remained to be discovered. In this study, cell viability was assessed using MTS assays and cell cycle was evaluated by(More)
