Fig. 6From: Cobalt protoporphyrin promotes human keratinocyte migration under hyperglycemic conditionsThe protective effect of CoPP pretreatment in HaCaT after exposing to LPS-containing media. a Time lapse images showing the migrated distance of CoPP-pretreated HaCaT after exposing to LPS-containing media (scale bar, 100 μm), b and the statistical analysis of the migrated distance of each sample at 20th hours of the migration assay. c The fluorescence probing of ZO-1 expressions in HaCaT that received LPS or CoPP pretreatment plus LPS (scale bar, 50 μm). d Statistic analysis of the fluorescence signals of ZO-1 in HaCaT that received either LPS or CoPP + LPS. The measured fluorescent intensities were normalized against the respective non-treatment group. **P < 0.01; ***P < 0.001Back to article page
