Metabolic Plasticity in Cell State Homeostasis and Differentiation of Cultured Human Corneal Endothelial Cells.
Investigative Ophthalmology & Visual Science 2016 August 2
Purpose: To clarify whether cultured human corneal endothelial cells (cHCECs), heterogeneous in their differentiation state, exhibit distinctive energy metabolism with the aim to develop a reliable method to sort cHCECs applicable for regenerative medicine.
Methods: The presence of cHCEC subpopulations (SPs) was verified via surface cluster-of-differentiation (CD) marker expression. Cultured HCEC metabolic extracts or corresponding culture supernatants with distinctive cellular phenotypes in regard to energy-metabolism-related functional markers c-Myc and CD44 were prepared and analyzed via capillary electrophoresis-tandem mass spectrometry. The metabolic requirements of heterogeneous SPs of cHCECs were also investigated.
Results: After successfully discriminating SPs, as verified via surface CD markers in terms of their secretory metabolites, we found that the CD44+++ SP with cell-state transition (CST) exhibited disposition for anaerobic glycolysis, whereas the CD44-SP without CST was disposed to mitochondria-dependent oxidative phosphorylation (OXPHOS). These results raised the possibility of establishing effective culture conditions to selectively expand mature cHCECs with a hexagonal cobblestone shape and inclination for mitochondria-dependent OXPHOS.
Conclusions: The findings of this study open a pathway for monitoring the disposition of cHCECs via their energy metabolism, thus leading to safe and stable regenerative medicine by use of metabolically defined cHCECs in cell-suspension form.
