The mean absolute difference between passage 3 and 7 versus the different technical variability cutoffs of a within chip; and b between chips. c Volcano plot of the mean difference between passage 7 and 3 versus –Log10(p-value) representing the biological variability. Red circles indicate the number of miRNA sequences that passed the biological variability filter (p-value <0.05). d Signal density distribution of the miRNA signals and the negative controls. e Hierarchical clustering heatmap of the significant miRNAs expression levels at passages 3, 5, and 7. Principal component analyses of the f unsupervised 2686 different miRNA sequences prior to analysis; and g supervised 12 statistically significant miRNA sequences
