Figure 1. Differential expression profile of miRNAs in hypertrophic scar tissues. (A) miRNAs differentially expressed in hypertrophic scar and normal tissues were detected using a gene microarray. (B) Expression levels of miRNAs in hypertrophic scar and normal tissues were detected using real-time PCR. ** P< 0.01 vs. normal tissues (C) Expression levels of miRNAs in hypertrophic scar fibroblasts, normal scar fibroblasts and normal fibroblasts were detected using real-time PCR. ** P< 0.01 vs. hypertrophic scar fibroblasts.
