The effects of poly I:C on HaCaT cell viability and collective migration. a Cell viability measured by formazan formation at 24, 48, and 72 h after the administration of poly I:C (n = 5). b Representative images showing collective HaCaT cell migration at 72 h after the scratch with mitomycin C pretreatment for 2 h, and remaining wound area in a 3 × 8 mm² rectangle (n = 3). Data are presented as the mean ± SEM. Grids = 1 × 1 mm². *p < 0.05 vs. control according to the Mann–Whitney test. ** p < 0.01 vs. control according to the Tukey-Kramer test. poly; poly I:C, Chloro; chloroquine. MMC; mitomycin C
