Effect of AgNPs on expression of differentiation markers.
Notes: (A) F9 cells were treated with or without RA (1 μM) for 72 h or AgNPs (6.125 or 12.5 μg/mL) for 24 h, and differentiation was observed by phase contrast microscopy. (B) Real-time quantitative PCR was performed to analyze the expression of various neuronal differentiation markers. The results are expressed as the mean ± standard deviation of three separate experiments. The treated groups showed statistically significant differences from the control group determined using Student’s t-test (***P<0.001).
Abbreviations: AgNPs, silver nanoparticles; RA, retinoic acid; PCR, polymerase chain reaction.
