Fig. 2.

Example ki67 and cleaved caspase-3 scoring of explant immunostaining (A) and sample explant micrographs immunostained for ki67 (B). (A) Normally distributed data are displayed as red dots, black error bars, the average and the standard deviation. Non-normally distributed data are displayed as black dots with blue error bars. Significant differences are indicated where * represents P ≤ 0.05 compared to DMSO, # corresponds to P ≤ 0.05 compared to OX + 5-FU. Each data point represents an average score from one field of view. Scoring was undertaken by 2 independent observers, and the scores averaged. (B) Sample ki67 explant micrographs shown at ×40 objective. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
