miR-370-3p regulated hASC osteogenesis by targeting HDAC4. a Bioinformatic analysis predicted the target relationship. b The expressions of HDAC4 were evaluated by RT-qPCR. c circ_0003204 siRNAs carried Cy3 reporter (red) and transfection efficiency was confirmed by fluorescence microscopy (scale bar = 100 μm). d Images of ALP and ARS stainings after transfection. e, f ALP and ARS activity analyses were detected. g RT-qPCR evaluated the mRNA expression levels of BGLAP after 7-day osteogenic induction of hASCs. h The expression of HDAC4 was regulated by circ_0003204.
