Effect of Shen Qi Wan medicated serum on wound healing of NRK-52E cells. (A) After wounding, cell migration was measured by the speed of wound healing. For each scratch, 3 different visual fields were recorded for measurement. The line on images was indicating the wound edges (red, initial; blue, after 6 hours or 12 hours). The scale bar indicates 200 μm. (B) Statistical results for all treatment groups in wound healing assay. ## P<0.01 vs. the Serum-free group; * P<0.05, ** P<0.01 vs. the Blank Serum group.
