RNA aptamer 14 (Apt 14) inhibits porcine VSMC migration in the presence of contrast agent
Cells were cultured to confluence then subject to scratch wound injury and treated with PDGF-BB (5 ng/mL). Apt 14 was diluted in isotonic contrast agent at a concentration of 200 nM or 500 nM. (A) Wound confluence was measured by the Incucyte S3 system for more than 22 h. (B) Representative cell phase images were shown at 0 h and 22 h after PDGF exposure. The initial scratch wound and scratch wound area were masked in blue and yellow, respectively. Data were analyzed by two-way ANOVA, repeated measures, with Bonferroni post tests. ∗p < 0.05, ∗∗p < 0.01 vs. vehicle, #p < 0.05, ##p < 0.01 vs. PDGF. n = 4.
