A review of human studies identified 197 miRNAs associated with wound healing, burn wound healing, and scarring, with the mir-3150b-5p being downregulated in hypertrophic scar tissue compared to normal tissue [Siu et al. DOI:10.1111/wrr.13100]. A study in humans demonstrated that the mir-3150b-5p was identified as a differentially expressed microRNA shared across two pairs of monozygotic twins, suggesting its potential role in distinguishing genetically identical individuals [Xiao et al. DOI:10.1016/j.fsigen.2019.05.003].
