A review of human studies identified 197 miRNAs associated with wound healing, burn wound healing, and scarring, with specific expression patterns validated in human skin tissue and cell lines using qRT-PCR, microarrays, and next-generation sequencing [Siu et al. DOI:10.1111/wrr.13100]. A study in humans demonstrated that the miR-3182 was differentially expressed and shared across three pairs of monozygotic twins, suggesting its potential role as a biomarker for distinguishing genetically identical individuals [Xiao et al. DOI:10.1016/j.fsigen.2019.05.003].
