microRNA-Seq of the OB
Exosomes was observed in the cytoplasm under a fluorescence microscope, confirming that exosomes could be taken up by osteoblasts. In total, 2590 miRNAs were found, of which 47 miRNAs were differentially expressed. Among these 47 miRNAs, 35 miRNAs were up-regulated and 12 miRNAs were down-regulated.
