The characteristics of stromal fibroblasts after treatment with culture media from HeLa cells (HeLa CM) and TGF-β1.

<p>The level of transcriptional change was examined by real-time RT-PCR. A: the expression of <i>miR-21</i> was significantly up-regulated at 24 and 48 h after HeLa CM or TGF-β1 treatment. B and C: the expression of <i>IL-6</i> and alpha-<i>SMA</i> was significantly up-regulated at 48 h after HeLa CM or TGF-β1 treatment. D: <i>PDCD4</i> was significantly down-regulated at 48 h after HeLa CM or TGF-β1 treatment. (*: significant differences from control at <i>P</i><0.05)</p>
