Figure 2From: Fractionated irradiation induced radio-resistant esophageal cancer EC109 cells seem to be more sensitive to chemotherapeutic drugsCell proliferation assay of EC109 and EC109/R cells. Cells were cultured in 96-well plates for 0, 24, 48 and 72 h. Cell viability was determined by MTT assay. Each point represents the mean ± SD of triplicate experiments (p > 0.05).Back to article page
