Fig. 1: Effects of miR-221-3p on wound healing in normal and diabetic mice.

Representative photomicrographs (a) and summary data (b, c) showing changes in the area of excisional wounds on days 0, 2, 4, 8, and 10 in normal mice injected with either miRNA mimic negative control (Ctrl) or miR-221-3p agomir (miR-221-3p) and diabetic mice injected with either miRNA mimic negative control (DM-Ctrl) or miR-221-3p agomir (DM-miR-221-3p). The smallest scale division of the ruler is 1 mm in a. Data are presented as mean ± SEM, n = 7–8. *P < 0.05, **P < 0.01 for Ctrl vs. miR-221-3p. #P < 0.05, ##P < 0.01 for DM-Ctrl vs. DM-miR-221-3p.
