Fig. 4: miR-21a-5p is enriched in MSC-Exos.

A Exosomal miRNA sequencing revealed the top 20 most abundant miRNAs in MSC-Exos. B Relative percentages of different miRNAs in total miRNA reads. C qPCR analysis of the top 5 miRNAs in MSC-Exos (n = 4). D Relative expression of the top 5 miRNAs in MSC-Exos in kidney tissues from sham, UUO and MSC-Exo-treated mice (n = 4 mice per group). Data are presented as the mean ± SD from three independent experiments. **p < 0.01.
