| Study Title | Sub-nanoliter metabolomics via mass spectrometry to characterize volume-limited samples - MSC |
| Study Summary | The human metabolome provides a window into the mechanisms and biomarkers of various diseases. However, because of limited availability, many sample types are still difficult to study by metabolomic analyses. Here, we present a new mass spectrometry (MS)-based metabolomics strategy that only consumes sub-nanoliter sample volumes. The approach consists of combining a customized metabolomics workflow with a pulsed MS ion generation method, known as triboelectric nanogenerator inductive nanoelectrospray ionization (TENGi nanoESI) MS. A second example to illustrate TENGi MS capabilities involves rare cell metabolomics of cultured mesenchymal stromal cells (MSCs), a cell type that has shown potential for treating a variety of chronic diseases. Examination of metabolic changes of MSCs cultured under conditions that may impact in vitro therapeutic activity, such as aggregate culture, or preconditioning with interferon gamma (IFN- γ)13, is critical for identifying attributes of cell quality. Reducing cell numbers required to perform MSC metabolomic analysis is essential for improving the manufacturing of highly therapeutic MSCs without significantly impeding production. |
