Mesenchymal stem cells (MSCs) reside within the stromal compartment of bone marrow and represent a plastic cell population for which pro-haematopoietic, immunosuppressive and regenerative properties are poorly characterized. A characterization of MSC preparations was carried out with each passage in MSCGM or α-MEM + 20% FBS expansion media. We obtained 3 times more cells after 5 passages in MSCGM than in α-MEM + 20% FBS. We analysed the phenotype of MSCs after each passage by flow cytometry. At all passages and in both media cells were tested negative for CD45, strongly positive for CD73 and CD90 antigens and weakly positive for CD105 and CD106 antigens. We wanted to assess the MSC ability to differentiate into adipocytes, osteoblasts and chondroblasts. At all tested passages and in both media, MSCs differentiated in these three tissues when they were placed in the adequate induction medium. We used RayBio® Human Cytokine Antibody Array to analyse the presence of several cytokines in MSC-conditioned medium. At all passages and in both media, IL-6, IL-8 and VCAM-1 were more strongly expressed than the other cytokines. We used the CFU-F assay to evaluate the frequency and purity of MSCs in culture. We observed that CFU-F number reached a maximum at passages 3 and 4 after expansion in both MSCGM and in α-MEM + 20% FBS. We also observed a greater proportion of CFU-F for the cells expanded in MSCGM compared to the cells expanded in α-MEM + 20% FBS. To assess the haematopoietic supporting ability of MSCs, long term cultures were performed. We observed more colony-forming cells when long-term cultures were done with 1st and 2nd passages MSCs than when cultures were done with 3rd, 4th and 5th passages MSCs. In NOD/SCID mice we transplanted CD34+ uncultured cells or the expansion product of CD34+ cells co-cultured for one week with MSCs. Human chimerism was present in all conditions. We observed a greater human chimerism when CD34+ cells were co-cultured with MSCs from passage 4 than in the other conditions. In all conditions simultaneous expression of CD19 or CD33 antigens on human CD45+ cells demonstrated the presence of repopulating cells with lympho-myeloid potential. Despite the fact that MSCs had the same phenotype, differentiation potential and cytokine secretion profile at each passage and in both media, MSCs did have neither the same capacity to form CFU-F nor the same capacity to support haematopoiesis in vitro and in vivo.

If we easily categorize sung performances as “in tune” or “out of tune”, it is not so evident to explicitly describe on which criteria our evaluation is based. This presentation reports recent work on pitch accuracy perception in a melodic context. The results allow to refine the notion of pitch accuracy and therefore to design objective tools for the evaluation of singer quality. [less ▲]

Dans un contexte de croissance des recompositions conjugales après divorce, la prise en charge des tâches parentales constitue un défi inédit, où il s'agit pour les uns de retrouver des repères bien connus, et pour les autres, d'imaginer un nouvel ordre éducatif. Une nouvelle histoire doit alors être créée, et dans ce "bricolage", chacun ne dispose pas des mêmes ressources pour trouver sa place. [less ▲]

Current therapies with pegylated interferon and ribavirin are effective to eradicate the virus C. Improvements in the treatment are foreseen in the near future with combination of the current treatment with antiviral therapies (antiproteases, antipolymerases). Eradication of the virus, when obtained, has a favorable impact on an individual basis. However, to reduce the mortality related to the virus C at a population level, an important point is the accessibility to the therapy. It has been calculated that the impact of better management of hepatitis C to reduce mortality is minimal, due to a poor accessibility to the therapy. To obtain a significant additional reduction of mortality, a better screening, a better access to therapy and a better compliance are crucial. [less ▲]
