We analyzed miRNA from control and TGFβ-treated exosomes in the miScript miRNA PCR Array Rat Fibrosis Pathway focused panels (Qiagen) and found that expression levels of many fibrosis-related miRNAs were altered in TGFβ-treated FB derived exosomes as compared to control exosomes (Figure 6A). Here, TGFB1 is linked to fibrosis.
