Effect of Functionalized Carbon Nanotubes and their Citric Acid Polymerization on Mesenchymal Stem Cells In Vitro

Figure 5

Bar plots of the proliferation effects on MSCs versus incubation time at different CNT concentrations for the four types of CNTs and a control sample. At concentrations of 10 and 100 ng/ml, fMWNTs and PMWNTs promote cell proliferation; contrarily, fCNxs and PCNx causes inhibition. A 1000 all CNTs show a cytotoxic effect. The trypan blue escalation was performed to evaluate the cell viability. Data are representative of three independent experiments and are expressed as the mean of at least three experiments with p < 0.05.
