More genes are significantly expressed in skin wounds than in the tongue wounds. One mm punch wounds were made on BALB/c mice skin and tongue. Wounds and surrounding tissues were harvested at 6 h, 12 h, and days 1, 3, 5, 7, and 10. Total RNA was extracted. Microarray was carried out using Affymetrix GeneChip arrays. A one-way ANOVA was used to identify significantly differentially expressed gene sets across all time points after wounding (FDR < 0.05). Figure shows the numbers of significantly expressed probes at each time point compared to normal tissues.
