Abstract:

Bone marrow mesenchymal stromal cells (MSCs) suppress immune cell responses and have beneficial effects in various inflammatory-related immune disorders. A therapeutic modality for systemic inflammation and its consequences is not available yet. Thus, this work investigates the therapeutic effects of MSCs in injury models induced by lipopolysaccharide (LPS) or burn. Gene expression was analyzed in MSCs when exposed to inflammatory serum from injured animals and it showed remarkable alterations compared to normal culture. In addition, injured animals were transplanted intramuscularly with MSCs. Forty-eight hours after cell transplantation, kidney, lung, and liver were analyzed for infiltration of inflammatory cells and TUNEL-expressing cells. Results showed that MSCs attenuate injury by reducing the infiltration of inflammatory cells in various target organs and by reducing cell death. These data suggest that MSCs emerge as key regulators of immune/inflammatory responses in vivo and as attractive candidates for cell-based treatments for systemic inflammatory-based disorders.

More about this publication?
  • Cell Transplantation publishes original, peer-reviewed research and review articles on the subject of cell transplantation and its application to human diseases. To ensure high-quality contributions from all areas of transplantation, separate section editors and editorial boards have been established. Articles deal with a wide range of topics including physiological, medical, preclinical, tissue engineering, and device-oriented aspects of transplantation of nervous system, endocrine, growth factor-secreting, bone marrow, epithelial, endothelial, and genetically engineered cells, among others. Basic clinical studies and immunological research papers are also featured. To provide complete coverage of this revolutionary field, Cell Transplantation will report on relevant technological advances, and ethical and regulatory considerations of cell transplants. Cell Transplantation is now an Open Access journal starting with volume 18 in 2009, and therefore there will be an inexpensive publication charge, which is dependent on the number of pages, in addition to the charge for color figures. This will allow work to be disseminated to a wider audience and also entitle the corresponding author to a free PDF, as well as prepublication of an unedited version of the manuscript.
