Percent migration of HUVEC and SMC across 48 h on polystyrene. a HUVEC migration on polystyrene surface at 4, 24 and 48 h; shown in percent migration when compared to baseline migration at 0 h. Out-migration and in-migration were significantly higher than scrape wound migration at 4 h, (p < 0.0001 and p = 0.0183). Out-migration was significantly lower than scrape wound migration at 24 h (p = 0.0014). b SMC migration on polystyrene surface at 4, 24, and 48 h; shown in percent migration when compared to baseline migration at 0 h. SMC out-migration was significantly lower than scrape wound migration at 4 (p = 0.0020), 24 (p = 0.0464) and 48 (p = 0.0003) hours. ☐ symbol outline indicates statistical significance (p-values < 0.05).
