title: 31P magnetic resonance spectroscopy of endothelial cells grown in three-dimensional matrigel constructs as an enabling platform technology: II. The effect of anti-inflammatory drugs on phosphometabolite levels.
abstract: In the accompanying study, the authors presented phosphometabolite patterns of endothelial cells grown under three-dimensional (3D) conditions using (31)P magnetic resonance spectroscopy (MRS). Here the authors describe the effect of nonsteroidal anti-inflammatory drugs (NSAIDs), using this enabling platform technology, which is relevant for evaluating drug effects in tissue-engineered endothelial constructs. Treatment with indomethacin significantly changed the phosphometabolite fingerprint in this endothelial model, by, respectively, increasing (81%) and decreasing (42%) glycerophosphocholine (GPC) and phosphomonoesters (PM). Furthermore, a safer approach using a NSAID prodrug was also demonstrated in this study with a indomethacin phospholipid-derived prodrug (DP-155). Like the parental drug, DP-155 increased and decreased the levels of GPC and PM by 100% and 20%, respectively. These changes represent useful biomarkers to monitor NSAID effects on endothelized tissue-engineered constructs for the purpose of controlling endothelial cell survival and inflammation upon implantation.
