Fig. 2

Microarray assay of differential miRNA in exosomes derived from RBC suspensions. a Heatmap of differential miRNA expressed in exosomes stored for week 5 vs. week 1. Each column represents an RBC suspension sample, and each row represents a kind of miRNA. The color describes the expression level of each miRNA in each sample, where red indicates a high level of expression and where green indicates a low level of expression. b Volcano plot shows the distribute expression of differential miRNAs. Different colors correspond to the levels of expression, where red represents significantly differential miRNA (P < 0.05)
