Figure 2. miRNA contents of SPEVs. (A) Read mapping distribution of the short noncoding RNA types in SPEVs. (B) Proportion of known and predicted miRNAs detected in pig SPEVs. (C) Distribution of the miRNA lengths. (D) Number of miRNAs with different expression levels. Most of the miRNAs were expressed at low levels, and 16 miRNAs were expressed at high levels (above 10,000 TPM).
