The Kaplan-Meier curve demonstrates increased survival of cct3A RNAi animals when treated with DTT under starved conditions. Percentages indicate the number of survivals at the indicated time points. Three asterisks indicate p < 0.001 with log-rank (Mantel-Cox) test. Images are representative surviving animals for the different conditions at the displayed time point of regeneration. At the bottom are the number of planarians with the phenotype shown. The rest of planarians are dead at the displayed time point.
