mRNA levels of <i>VEGF-A, TGF-β1</i> and <i>IL-6</i> in different treatment groups during wound healing.

<p>AgNP/NSP treatment also modulates the expression of cytokine mRNAs in wounded skin. The levels of <i>VEGF-A</i>, <i>TGF-β1</i> and <i>IL-6</i> mRNA expression from mice of different treatment groups in both acute thermal injury at day 7 (a) and excision wound at day 15 (b) were examined by RT-PCR. Relative band intensities of different groups were calculated by a densitometer and are demonstrated by the values under the bands. The data shown are representative of three independent experiments.
