The species origin of the serum in the culture medium influences the in vitro toxicity of silica nanoparticles to HepG2 cells
Fig 5
Real-time cell index (CI) monitoring of HepG2 cells (n = 3) exposed to A) 50 μg/mL, B) 100 μg/mL M-MSNs, in a pristine state or covered with serum proteins, for 115 hours.
All curves represent the mean of three curves with recorded standard deviations at each time-point. The black arrow represents the starting point of exposure. Cell index was normalized to baseline (control cells).
