The localization of <i>miR-21</i> in invasive cervical cancer tissues.

<p>A and B: tissue sections from cervical cancer samples were incubated with DIG-labeled locked nuclei acid (LNA) probe to <i>miR-21</i>. Strong signals were observed in the stroma. The signal was also seen at the rim of cancer cells adjacent to the stroma (Bar: 100 μm). C: <i>RNU6B</i> staining in cervical cancer and stromal nuclei (Bar: 50 μm). D: cervical cancer negative control staining using a ‘scramble’ LNA probe (Bar: 50 μm).</p>
