Fig. 3. MTT assay for cell viability analysis. L-929 cells were treated with UHMWPE, Pure-Ti, and Ti-6Al-4V for 24 hours. Cell viability was determined by MTT assay, and results are expressed as a percentage of the control group. Data are presented as the mean ± standard deviation of three independent experiments. UHMWPE, ultra-high molecular weight polyethylene.
