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-3611 was differentially expressed and shared across two pairs of monozygotic twins, with microarray analysis of blood samples from 18 twin pairs identifying 545 differentially expressed miRNAs, including this biomarker, and subsequent qRT-PCR validation on selected miRNAs showing consistent expression patterns [Xiao et al. DOI:10.1016/j.fsigen.2019.05.003].
