Recently, microRNAs (miRNAs) which are non-coding small RNAs that negatively control gene expressions displayed an important role in the regulation of gene expression in various cells of the skin, including stem cells, immune cells, and keratinocytes (Xu et al., 2014). Moreover, several miRNAs were shown to be differentially expressed in diabetic skins and their expression levels varied during the wound healing process (Madhyastha et al., 2012). For instance, miRNA-126 depletion causes defective endothelial cell proliferation, migration, and angiogenesis contributed by elevated levels of miRNA-503 which is specially grown in diabetes resulting in impaired wound healing via persistent
