Figure 6: The identification of 7 miRNAs by stem-loop RT-PCR. The mRNA expression of 7 miRNAs was confirmed. The sizes of the PCR products were approximately 55 bp. 18s rRNA was used as a positive control. M: 20 bp DNA ladder maker; 1–12: PC-3p-186_7748, PC-5p-970_1302, PC-5p-108_13860, PC-5p-14_74120, hsa-miR-142-3p_R-1, fru-miR-204, fru-miR-126, 18s rRNA.
