生化/生理作用

L-谷氨酰胺是一种必需氨基酸，作为细胞培养过程中主要的能量来源而成为培养基的重要组分。L-谷氨酰胺在干粉及冷冻溶液的状态下极为稳定。然而，L-谷氨酰胺在液体培养基或储存溶液中均会相对较快的降解。最佳的细胞表现通常需要在使用前向培养基中添加L-谷氨酰胺补充剂。

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
