Figure 5: Cell viability of C2C12 cell line after treatment with polymers at various doses. Cells were seeded in 96 well plates at an initial density 1×104 cells /well. Cell viability was determined by MTS assay (The percentage is the average of triplicate experiments. The concentration of polymers are 4, 10, 20 µg/ml from left to right. (*p<0.05 compared with untreated cell as control, two-tailed Student’s t-test, error bar represents standard deviation, n=3).
