Energy Metabolism and Lipidome Are Highly Regulated during Osteogenic Differentiation of Dental Follicle Cells

Expression of glycolysis and citric acid cycle markers during osteogenic differentiation of DFCs. (a) DFCs were cultured in osteogenic differentiation medium (ODM), BMP2 differentiation medium, or control medium (DMEM) for one, seven, 14, and 28 days before protein expression of the glycolysis markers hexokinase I, hexokinase II, phosphofructokinase, glycerinaldehyd-3-phosphat-dehydrogenase (GAPDH), pyruvate kinase M1/2, pyruvate kinase M2, and lactate dehydrogenase A, and protein expression of the citric acid cycle markers aconitase 2, isocitrate dehydrogenase 1, isocitrate dehydrogenase 2, dihydrolipoamide succinyltransferase (DLST), fumarase, citrase synthase, mitochondrial pyruvate carrier 1, and mitochondrial pyruvate carrier 2 were determined by western blot analysis. Quantification results and statistical analysis are shown in the Supplementary Table 2. (b–d) DFCs were cultured in osteogenic differentiation medium (ODM), BMP2 differentiation medium, or control medium (DMEM) for seven days before the amount of produced L-lactate (b) and hexokinase activity (c) were determined as markers of glycolysis and malate dehydrogenase activity was measured (d) as marker of citric acid cycle. Results are shown as , and Student’s -test was performed to compare differentiation medium with control medium. , .
