Identification of BSMCs and miRNA transfection. a Under a fluorescence microscope, almost all cells were stained green, indicating the cytoskeleton, and blue, indicating the nucleus (magnification: × 200). b The transfection efficiencies of miR-199a-3p, miR-219c-5p and miR-3572-3p were detected by RT-qPCR. b The effect of miR-199a-3p, miR-219c-5p and miR-3572-3p on FN1 was detected by RT-qPCR. The findings were from three separate experiments. The data are expressed as the means ± SD.
