Metabolites Interrogation in Cell Fate Decision of Cultured Human Corneal Endothelial Cells

PURPOSE: Aiming to clarify the metabolic interrogation in cell fate decision of cultured human corneal endothelial cells (cHCECs). METHODS: To analyze the metabolites in the culture supernatants (CS), 34 metabolome measurements were carried out for mature differentiated and a variety of cHCECs with...

description PURPOSE: Aiming to clarify the metabolic interrogation in cell fate decision of cultured human corneal endothelial cells (cHCECs). METHODS: To analyze the metabolites in the culture supernatants (CS), 34 metabolome measurements were carried out for mature differentiated and a variety of cHCECs with cell state transition through a facility service. Integrated proteomics research for cell lysates by liquid chromatography−tandem mass spectrometry (LC-MS/MS) was performed for 3 aliquots of each high-quality or low-quality cHCEC subpopulations (SP). The investigations for the focused genes involved in cHCEC metabolism were performed by using DAVID and its options “KEGG_PATHWAY.” RESULTS: The clusters of metabolites coincided well with the distinct content of CD44−/+ SPs. Both secreted pyruvic acid and lactic acid in the CS were negatively correlated with the content of high-quality SPs. Lactic acid and pyruvic acid in the CS exhibited the positive correlation with that of Ile, Leu, and Ser, whereas the negative correlation was with glutamine. Platelet-derived growth factor-ββ in the CS negatively correlated with lactic acid in CS, indicating indirectly the positive correlation with the content of CD44−/+ SPs. Upregulated glycolytic enzymes and influx of glutamine to the tricarboxylic acid cycle may be linked with a metabolic rewiring converting oxidative metabolism in mature differentiated CD44−/+SPs into a glycolytic flux-dependent state in immature SPs with cell state transition. CONCLUSIONS: The findings suggest that the cell fate decision of cHCECs may be dictated at least partly through metabolic rewiring.
