A review of human studies identified 197 miRNAs associated with wound healing, burn wound healing, and scarring, with specific miRNAs showing altered expression in human skin tissue samples post-burn, during healing, and in hypertrophic scar tissue [Siu et al. DOI:10.1111/wrr.13100]. A study in humans demonstrated that the miR-610 was differentially expressed and shared across two pairs of monozygotic twins, suggesting a role in distinguishing genetically identical individuals [Xiao et al. DOI:10.1016/j.fsigen.2019.05.003].
