Expression of RANKL (A), OSX (B), OPG (C), NANOG (D), OCT-4 (E), SOX2 (F), FABP4 (G), LPL (H), ADIPOQ (I), Aggrecan (J), COL2A1 (K) and SOX9 (L) transcripts were determined in undifferentiated and osteogenic differentiated hMSC after the administration of modafinil (11.2 µg/mL), atomoxetine (0.9 µg/mL) and guanfacine (17.7 ng/mL) for 7 days by real-time quantitative PCR. Shown are means ± standard deviation of three independent experiments with six biological replicates. Significance in difference between the groups was determined by ANOVA followed by Tukey’s post hoc tests.
