Evidence of the production of anti-MOG-immunoglobulins within antisera when mice were inoculated with MOG peptide. (A) Purified EAE-AS (IgG from EAE-AS) and unpurified EAE-AS identified bands of the same molecular weight on NPCs substrate. Western blot of recombinant MOG as SDS-PAGE substrate (B) and ICC of EL4-MOG cells (C) revealed the real existence of anti-MOG-immunoglobulins within EAE-AS. One band was yielded (above 20kDA) when recombinant MOG was probed with EAE-AS and anti-MOG (positive control) (B). EAE-AS and anti-MOG showed high levels of binding on EL4-MOG cells (DAB staining), whereas NAIVE-AS did not bind (C). Magnification=40X, Scale=100Οm. (JPEG 344 kb

Characterization of In Vitro Expanded Bone Marrow-Derived Mesenchymal Stem Cells Isolated from Experimental Autoimmune Encephalomyelitis Mice

Extensive experimental studies indicate that autologous bone marrow mesenchymal stem cells (BMSCs) are able to ameliorate experimental autoimmune encephalomyelitis (EAE) and potentially multiple sclerosis. However, the impact that the inflammatory environment present in EAE may have on the biological properties of BMSCs expanded in vitro for transplantation is yet to be clarified. It was investigated whether BMSCs isolated from EAE-induced C57bl6/J mice and expanded in vitro preserve the properties of BMSCs isolated from healthy donors (BMSCs-control). The mesenchymal origin, the differentiation potential, and the transcriptional expression profile of six histone-modifying genes were studied in both groups of BMSCs. BMSCs-EAE exhibited distinct morphology and larger size compared to BMSCs-control, higher degree of proliferation and apoptosis, differences in the adipogenesis and the osteogenesis induction, and differential expression of stromal markers and markers of progenitor and mature neuronal/glial cells. Moreover, BMSCs-EAE exhibited different expression patterns on a number of histone-modifying genes compared to controls. We recorded manifold differences, both phenotypical and functional, of in vitro expanded BMSCs-EAE in comparison to their healthy donor-derived counterparts that may be attributed to the inflammatory environment they originated from. Whether our findings may be of any clinical relevance needs to be clarified in future studies, in vivo
