Total RNA from the cells and exosomes was isolated using the TRIzol reagent (Life Technologies, Carlsbad, CA, USA) or E.Z.N.A.™ miRNA Kit (Omega Bio-tek, Norcross, GA, USA) in accordance with the manufacturer’s instructions. First-strand cDNA was synthesized from RNA primed by oligo (dT) using M-MLV reverse transcriptase. The RT-qPCR assay for multiple genes was performed with the miScript SYBR Green PCR Kit by an CFX96™ Real-Time PCR Dectection System (BIO-RAD, Hercules, CA, USA). The primer of miRNA sequences is listed in Table 1. The expression levels of U6 snRNA were used to normalize the relative amount of miRNA (RT-Primer 5’-TTCACGAATTTGCGTGTCATC-3’, Forward 5’-CGCTTCGGCAGCACATATAC-3’, Reversed 5’-TTCACGAATTTGCGTGTCATC-3’). The fold-change of miRNA was calculated using the 2−ΔΔCT method.
