La L-glutamine est un acide aminé essentiel qui sert d′importante source d′énergie aux cellules en culture et constitue un composant crucial des milieux de culture. La L-glutamine est très stable sous forme de poudre sèche ou de solution congelée. Elle se dégrade toutefois assez rapidement dans les milieux liquides et les solutions mères. L′atteinte de performances cellulaires optimales nécessite généralement l′ajout d′un supplément en L-glutamine au milieu avant utilisation.

This study sought to identify critical determinants of mesenchymal stem cell (MSC) potency using in vitro and in vivo attributes of cells isolated from the bone marrow of age- and sex-matched donors. Adherence to plastic was not indicative of potency

Cell-matrix adhesions are central mediators of mechanotransduction, yet the interplay between force and adhesion regulation remains unclear. Here we use live cell imaging to map time-dependent cross-correlations between vinculin-mediated tension and adhesion complex area, revealing a plastic, context-dependent relationship. Interestingly

Helminth parasites remain one of the most common causes of infections worldwide, yet little is still known about the immune signaling pathways that control their expulsion. C57BL/6 mice are chronically susceptible to infection with the gastrointestinal helminth parasite Heligmosomoides polygyrus.

Although the locations of promoters and enhancers have been identified in several cell types, we still have limited information on their connectivity. We developed HiCap, which combines a 4-cutter restriction enzyme Hi-C with sequence capture of promoter regions. Applying the

Osteopontin (OPN) is a multifunctional cytokine critically involved in cardiac fibrosis. However, the underlying mechanisms are unresolved. Non-coding RNAs are powerful regulators of gene expression and thus might mediate this process. OPN and miR-21 were significantly increased in cardiac biopsies
