Figure 2. Heatmap of microRNA expression profiles in the developing porcine brain, with developmental stage being the main source of variation.

Developmental stage-dependent microRNA (miRNA) expression determines the clustering. Statistically significant miRNAs (p-value <9.39E⁻⁰⁵, selected by ANOVA test) are presented. Three replicates from each stage and tissue cluster together. The blue color denotes downregulated expression and the red color denotes upregulated expression level from the mean. Columns and rows represent samples and particular miRNAs, respectively. F50 and F100 stand for fetus gestation day 50 and fetus gestation day 100, respectively.
